The validity of clinic-based samples in approximating out-of-care HIV-infected populations.

Tremendous strides have been made in the diagnosis and treatment of human immunodeficiency virus (HIV); perhaps now the largest barrier to controlling HIV is retaining those diagnosed in care. Data on out-of-care populations are needed to develop effective retention methods, yet obtaining these remains methodologically challenging due to inherent difficulties in sampling. The purpose of this study was to evaluate whether individuals identified by two sampling methods commonly used to approximate out-of-care populations were significantly different from a sample of newly identified out-of-care persons. We compared medical records of 345 out-of-care persons identified by a novel population-based health information exchange who had not received CD4 or viral load monitoring in >1 year with: medical records from a randomly selected, time-matched sample of 488 HIV-infected persons with at least one HIV care visit in the past 5 years, and interviews with 382 participants from a time-matched clinic-based convenience sample. Newly identified out-of-care persons were significantly different from both proxies with respect to demographic, clinical, and utilization characteristics, suggesting that samples of in-care proxy persons are inadequate to describe those not engaged in care. Novel approaches to sampling out-of care populations are urgently needed in order to better understand these populations and ways to improve retention and slow the HIV/AIDS epidemic.

An unusual case of lower trunk brachial plexus zoster reactivation.

We discuss the case of a 42-year-old woman who presented with severe left cubital tunnel neuropathic pain and subsequently developed a vesicular rash spanning the C8-T1 dermatomal distribution. These symptoms resolved after initiation of acyclovir, highlighting VZV brachial plexopathy as a potentially treatable etiology of acute onset severe neuropathic pain.

Techniques and Applications of Lower Extremity Feminization and Masculinization.

Background: Significant differences exist between feminine and masculine lower extremities, and this region contributes to gender dysphoria in transgender and nonbinary individuals. Methods: A systematic review was conducted for primary literature on lower extremity (LE) gender affirmation techniques as well as anthropometric differences between male and female lower extremities, which could guide surgical planning. Multiple databases were searched for articles before June 2, 2021 using Medical Subject Headings. Data on techniques, outcomes, complications, and anthropometrics were collected. Results: A total of 852 unique articles were identified: 17 met criteria for male and female anthropometrics and 1 met criteria for LE surgical techniques potentially applicable to gender affirmation. None met criteria for LE gender affirmation techniques specifically. Therefore, this review was expanded to discuss surgical techniques for the LE, targeting masculine and feminine anthropometric ideals. LE masculinization can target feminine qualities, such as mid-lateral gluteal fullness and excess subcutaneous fat in the thigh and hips. Feminization can target masculine qualities like a low waist-to-hip ratio, mid-lateral gluteal concavity, calf hypertrophy, and body hair. Cultural differences and patient body habitus, which influence what is considered "ideal" for both sexes, should be discussed. Applicable techniques include hormone therapy, lipo-contouring, fat grafting, implant placement, and botulinum toxin injection, among others. Conclusions: Due to lack of existing outcomes-based literature, gender affirmation of the lower extremities will rely on application of an array of existing plastic surgery techniques. However, quality outcomes data for these procedures is required to determine best practices.

Morphometric Outcomes of Nonsyndromic Sagittal Synostosis following Open Middle and Posterior Cranial Vault Expansion.

BACKGROUND: This study aimed to quantify the change in three-dimensional skull morphometrics for patients with sagittal synostosis at presentation, after surgery, and at 2-year follow-up. METHODS: Computed tomography scans from 91 patients with isolated SS were age-, sex-, and race-matched with those from 273 controls. The authors performed vector analysis with linear regressions to model the effect of open middle and posterior cranial vault remodeling on cranial shape and growth. RESULTS: Anterior cranial volume, bossing angle, and frontal shape were not changed by surgery but normalized without surgical intervention by 2 years. Biparietal narrowing and middle cranial volume were corrected after surgery and maintained at 2 years. Occipital protuberance was improved after surgery and normalized at 2 years. Posterior cranial volume was decreased by occipital remodeling and remained slightly lower than control volumes at 2 years, whereas middle vault volume was larger than in controls. Residual deformities that persisted at 2 years were decreased superolateral width at the level of opisthion and increased anterosuperior height (vertex bulge). Linear models suggested older age at surgery resulted in more scaphocephaly and enlarged posterior cranial vault volumes at 2 years but did not affect other volume outcomes. Preoperative severity was the variable most predictive of 2-year morphometrics. CONCLUSIONS: Initial severity of sagittal synostosis deformity was the best predictor of 2-year morphometric outcomes. Upper posterior cranial width decreases with time after surgery and an anterior vertex bulge can persist after open surgery, but frontal dysmorphology self-corrects without surgical intervention. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Dual Innervation in Anterolateral Thigh (ALT) Phalloplasty: Consider the Femoral Perforating Nerves.

Sensation following anterolateral thigh (ALT) phalloplasty is traditionally viewed as inferior to sensation following radial forearm phalloplasty, potentially due to fewer nerve coaptations performed. Neural anatomy of the ALT is well described, with branches of the femoral nerve innervating the medial flap. The purpose of this article is to draw attention to these nerves as a potential source of additional coaptation in ALT phalloplasty allowing for dual flap innervation. Methods: A PRISMA literature review was conducted to assess nerve coaptations used in ALT phalloplasty. Anatomic location and territory of the nerves of the thigh in ALT phalloplasty cases are reviewed. Results: Seventeen articles discuss ALT phalloplasty innervation, and 16 mention the use of only one nerve coaptation with the lateral femoral cutaneous nerve. In our experience performing ALT phalloplasty, perforating branch(es) of the femoral nerve are the first nerve(s) encountered on the medial border of the ALT flap lying on the fascia over the sartorius. With a flap design where the urethra is based laterally, the femoral perforating nerves can innervate a significant portion of the phallic shaft (medial flap), where sensation is most desired. Conclusions: It is common practice to perform only one nerve coaptation in ALT phalloplasty with the lateral femoral cutaneous nerve. However, perforating branches of the femoral nerve consistently innervate medial skin of the ALT. The authors propose that the femoral perforating nerves, when present, can be used as additional nerves for coaptation in ALT phalloplasty to allow for dual innervation.

Morphologic Differences in Sagittal Synostosis with Age before Surgery.

BACKGROUND: It is important to determine whether sagittal synostosis-associated scaphocephaly is static in the presurgical period, or whether there are morphologic differences with time to include in surgical decision-making. The authors' purpose was to perform cross-sectional analysis of cranial morphology before any surgical intervention in children with sagittal synostosis younger than 9 months compared to matched controls. METHODS: The authors performed morphometric analysis on computed tomographic scans from 111 untreated isolated sagittal synostosis patients younger than 9 months and 37 age-matched normal controls. The authors divided the patients into three age groups and performed statistical comparison between sagittal synostosis and controls for each group. RESULTS: Sagittal synostosis cephalic indices were stable and lower in patients than in controls across groups. Total cranial volume was equivalent, but sagittal synostosis patients had a greater posterior volume than controls at all ages and a smaller middle fossa volume at older ages. Pterional width was greater in sagittal synostosis patients than in controls for each age group. Frontal bossing vectors were most severe in the youngest age groups and least in the older group. Occipital protuberance was consistent across the age groups. CONCLUSIONS: Upper parietal narrowing and occipital protuberance were the consistent deformities across age groups, with the most parietal constriction seen in older patients. Frontal bossing was not consistent and was more severe in the younger patients. The authors did not detect significant pterional constriction, and the appearance of constriction is relative to adjacent morphology and not absolute. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Silicone granuloma mimicking Breast Implant Associated Large Cell Lymphoma (BIA-ALCL): a case report.

We describe the case of a 75-year-old woman with textured silicone implants who was referred to our institution with concern for implant rupture and Breast Implant Associated Anaplastic Large Cell Lymphoma (BIA-ALCL). After explantation and pathologic evaluation, she was diagnosed with silicone granuloma and adenitis, though her presentation mimicked BIA-ALCL.

Clinical resolution of severely symptomatic pseudotumor cerebri after gastric bypass in an adolescent.

Pseudotumor cerebri is a disease characterized by increased intracranial pressure, often manifested by headaches, and occasionally leading to severe visual impairment or even blindness. Most cases in adolescents, as in adults, are associated with obesity. We report a 16-year-old morbidly obese adolescent girl (body mass index 42.3 kg/m(2)) with severely symptomatic pseudotumor cerebri who had progressive visual field deficits and elevated intracranial pressure (opening pressure on lumbar puncture of 50 cm H(2)O) despite intensive medical management and placement of both ventriculoperitoneal and lumboperitoneal shunts. Six months after she underwent gastric bypass surgery, she had lost 43% of her excess body weight and had had near complete regression of her visual field deficits, along with normalization of her intracranial pressures. This case demonstrates the dramatic reversal of symptoms of pseudotumor cerebri with surgically induced weight loss. Gastric bypass should be considered as a treatment option for adolescents with severe and progressive pseudotumor cerebri.

Correlates of early sexual activity among Hispanic children in middle adolescence.

OBJECTIVE: We analyzed early sexual activity among Hispanic 14 to 15-year-old adolescents residing in a poor neighborhood in Puerto Rico. METHODS: Information from a sample of 325 adolescents was collected from a randomized sample of community households. Logistic regression analysis was used to identify the variables that help explained adolescents' sexual behavior. RESULTS: Adolescents whose parents reported poor communication and poor parent control were more likely to engage in early sexual activity that those peers that did not report this type of family relationship. Adolescents who reported poor parent bonding and lack of discipline were more likely to engage in early sexual relationships. CONCLUSIONS: Intervention and prevention programs need to be aware and address the role of the Hispanic culture in gender differences in early sexual activity in adolescence. If sexual norms related to gender role are changing in Puerto Rico, is a question that needs to be answered in future research.

Methamphetamine use following bariatric surgery in an adolescent.

Bariatric surgery is increasingly popular as a therapeutic strategy for morbidly obese adolescents. Adolescence represents a sensitive period of psychosocial development, and children with considerable weight loss may experience greater peer acceptance, accompanied by both positive and negative influences. Substance abuse exists as one of these negative influences. We present the case of an adolescent bariatric surgical patient who abused methamphetamines in the postoperative period, with consequent nutritional instability. A concerted effort must be made in the preoperative assessment of adolescent bariatric patients to delineate a history of illicit drug use, including abuse of diet pills and stimulants. Excessive postoperative weight loss or micronutrient supplementation non-compliance should raise a suspicion of stimulant use and appropriate screening tests should be performed. The consequent appetite suppression may manifest with signs of malnutrition such as bradycardia, hypotension, and weakness. Inpatient nutritional rehabilitation and psychiatric assessment should be considered.

Drug treatment disparities among Hispanic drug-using women in Puerto Rico and New York City.

This paper reports findings on 334 out-of-treatment drug users in Puerto Rico and 617 in New York City, at the 6-month follow-up interview of a Longitudinal Survey. Main outcomes were health care and drug treatment utilization since baseline, assessed by asking participants if they had received physical or mental health services (including HIV medications), and if they had been in methadone maintenance, inpatient or outpatient drug treatment, or drug treatment while incarcerated. Chi-square tests were used to evaluate associations between gender and the various correlates. Logistic regression was used to calculate the contribution of each variable in predicting use of drug treatment. The analysis suggests that women in both sites were likely to suffer from disparities in both health care and drug treatment utilization when compared with men, albeit women in New York utilized more drug treatment resources and were more embedded in the immediate family than their female peers in Puerto Rico. Further research to specify the impact of contextual factors at the organizational and community levels, among members of the same ethnic group residing in different sites, may prove valuable in identifying the health needs and the factors that impede or facilitate drug-using women in obtaining the most appropriate treatment. Findings from these studies can help in developing appropriate public health policy and science-based drug treatment programs to eliminate disparities such as the ones detected in this study.

Factors associated with drug treatment dropout among injection drug users in Puerto Rico.

This study examined factors associated with drug treatment dropout among injection drug users (IDUs) in Puerto Rico, a group that has contributed significantly to the self-sustaining AIDS epidemic in the island since the mid-1980s. A total of 557 IDUs were recruited from communities in a semirural region of Puerto Rico, as part of a longitudinal study testing the efficacy of a two-facet intervention model, based on motivational interviewing. Of 124 IDUs who had entered drug treatment at follow-up, 33 (26.6%) dropped out before completing all recommended sessions. Multiple logistic regression analysis showed that age, homelessness, and speedball use were significantly associated with drug treatment dropout. Conversely, participants who received the two-facet intervention were significantly less likely to drop out of drug treatment. Receiving psychiatric services also reduced the odds of treatment dropout. Improving adherence to drug treatment and reducing dropout rates are complex processes that need to be addressed at the individual behavioral and social support levels, as well as the program process and resource levels.

HIV risk behaviors and alcohol intoxication among injection drug users in Puerto Rico.

This paper reports results of an analysis of the association between alcohol intoxication and injection and sexual HIV risk behaviors among 557 Hispanic heroin and cocaine injectors, not in treatment, who were recruited in poor communities in Puerto Rico. Subjects were part of a longitudinal prevention-intervention study aimed at reducing drug use and HIV risk behaviors. Participants reported a high prevalence of co-occurring conditions, particularly symptoms of severe depression (52%) and severe anxiety (37%), measured by Beck's Depression Index and Beck's Anxiety Index, respectively. Alcohol intoxication during the last 30 days was reported by 18% of participants. Associations were found between alcohol intoxication and both injection and sexual risk behaviors. In the bivariate analysis, subjects reporting alcohol intoxication were more likely to inject three or more times per day, pool money to buy drugs, share needles, and share cotton. They were also significantly more likely to have a casual or paying sex partner and to have unprotected sex with these partners. After adjustment, sharing needles and cotton, having sex with a paying partner or casual partner, and exchanging sex for money or drugs were significantly related to alcohol intoxication. HIV prevention programs, to be effective, must address alcohol intoxication and its relation to injection and sexual risk behaviors as a central issue in HIV prevention among drug injectors.

Effects of combined counseling and case management to reduce HIV risk behaviors among Hispanic drug injectors in Puerto Rico: a randomized controlled study.

This study examined the effectiveness of a combined counseling and case management behavioral intervention, using motivational interviewing strategies, in engaging Hispanic injection drug users in treatment and reducing drug use and injection-related HIV risk behaviors. Follow up data are presented on 440 (79.0%) of 557 randomized participants, 6 months after the initial interview. Subjects in the experimental arm were significantly less likely to continue drug injection independent of entering drug treatment, and were also more likely to enter drug treatment. Subjects in both arms who entered drug treatment were less likely to continue drug injection. Among subjects who continued drug injection, those in the experimental arm were significantly less likely to share needles. Confirming the outcomes of this study in other Hispanic sites and populations could be a critical step towards reducing factors that contribute to the self-sustaining HIV/AIDS epidemic in Puerto Rico and communities in the U.S. mainland.

Accessing hard-to-reach populations: the illicit drug market as a workplace of the outreach worker in Puerto Rico.

This descriptive paper reports findings from a formative research study on the drug market as a workplace of the outreach worker in Puerto Rico, and outlines strategies used by outreach workers to enable them to work effectively in these sites. Data were collected via outreach worker focus groups and participant observations at drug market sites. A social system theoretical model was used for analyzing data on drug market sites, and results are reported in terms of three basic social system components: structure, culture, and process. The authors recommend utilizing outreach workers as part of prevention and treatment teams in organizations providing services to drug users, as well as other hard-to-reach populations such as street sex workers and the homeless.

Improved HIV-related outcomes associated with implementation of a novel public health information exchange.

PURPOSE: The purpose of this study was to evaluate HIV-related outcomes associated with use of a novel public health information exchange that was designed to identify out of care HIV-infected individuals seen within a large, integrated delivery network (IDN). METHODS: A novel, secure, bidirectional health care delivery-public health information exchange, the Louisiana Public Health Information Exchange (LaPHIE) was developed between a multi-geographical IDN and the Louisiana public health authority in response to the high proportion of out of care HIV-infected persons. The system provides real-time provider alerts when any HIV-infected person who has not had CD4 or HIV viral load (VL) monitoring in >1 year receives non-HIV care within the IDN, allowing immediate linkage to HIV specialty care. Persons identified over the first 30 months of the system's implementation were characterized using a case-cohort approach to compare out-of-care individuals with randomly sampled, time-matched in-care controls. RESULTS: Between 2/1/09 and 7/31/11, 549 alerts identified 419 unduplicated HIV-infected individuals without a CD4 count or VL in >1 year. Patients were identified at 60 clinics and alerts shown to 223 clinicians in 7 participating facilities. A quarter (24%) of those identified had not had a CD4 count or VL conducted since their initial diagnosis. Of the remaining 76% who had been in care previously, over half (55%) had been out of care for ≥18 months, with a median time of 19.4 months [IQR 15.0-32.5] since their previous visit. Following LaPHIE identification, 42% had CD4 counts<200 cells/mm(3) and 62% had VL>10,000 RNA copies/mL. Of the 344 patients with at least 6 months of follow up, 85% had at least one CD4 and/or VL test after being identified. CONCLUSIONS: The results of this study demonstrate that an information exchange can effectively facilitate engagement, re-engagement, and retention of out-of care HIV-infected persons in HIV specialty care. Within two years, we were able to observe significant improvements in HIV-related utilization and disease progression indices. Future programs should consider adopting this innovative strategy to improve HIV care at both the individual and population levels.

Severe anxiety symptomatology and HIV risk behavior among Hispanic injection drug users in Puerto Rico.

Despite an overall decrease in AIDS incidence in Puerto Rico, our studies continue to show high prevalence of HIV risk behaviors among injection drug users (IDUs). This study seeks to evaluate whether the occurrence of injection-related and sex-related HIV risk behaviors among IDUs in Puerto Rico varies with the presence of anxiety symptomatology. Subjects included 557 IDUs, recruited from street settings in poor neighborhoods in Puerto Rico. Symptoms of severe anxiety were reported by 37.1% of the study sample. Participants with severe anxiety symptoms were more likely to share needles, cotton, and rinse water; to pool money to buy drugs; and to engage in backloading, than those without severe anxiety symptoms. Participants with severe anxiety symptomatology were also more likely to practice unprotected vaginal or oral sex. The findings from this study alert HIV prevention and treatment programs to the need to address anxiety disorders within their programs.

Prevalence and correlates of hepatitis C virus infection among street-recruited injection drug users in San Juan, Puerto Rico.

Throughout the world, injection drug users (IDUs) are the group at highest risk for hepatitis C virus (HCV) infection. IDUs residing in the island of Puerto Rico and Puerto Rican IDUs residing in the U.S. mainland have been shown to be at very high risk of infection with HIV. However, the extent to which HCV infection has spread among IDUs in Puerto Rico is not yet known. The aims of this study were to estimate seroprevalence of HCV and to identify the correlates associated with HCV transmission. The sample was drawn through street outreach strategies and was comprised of 400 injection drug users not in treatment, living in the San Juan metropolitan area. HCV and HIV infection were detected by enzyme-linked immunosorbent assay and the results were confirmed by Western blot. Information on sociodemographics, drug use patterns, and risk behaviors was obtained through structured interviews. Bivariate analyses and multivariate logistic regression were used to assess covariates of infection with HCV. The prevalence of HCV infection was 89%. After controlling for sociodemographic characteristics, HCV infection was positively associated with increasing years of injection, injecting in a shooting gallery, tattooing in prison, and self-reported STD infection. Notably, IDUs who had initiated drug injection within the year prior to the study interview had an HCV infection rate of 57%. This study indicates that more aggressive educational programs are urgently needed to reduce the spread of HCV infection among IDUs in Puerto Rico.

Homelessness and HIV risk behaviors among drug injectors in Puerto Rico.

This report examines associations between homelessness and HIV risk behaviors among injection drug users (IDUs) in Puerto Rico. The study sample consisted of 557 IDUs who were not in treatment, recruited in inner-city neighborhoods of the North Metro Health Care Region. Subjects were categorized into three groups by residential status (last 30 days): housed, transitionally housed (living with friends, family, or others but considering themselves homeless), and on-the-street homeless (living on the street or in a shelter). Multiple logistic regression models were fitted to assess effects of residential status on each HIV risk behavior after adjusting for sociodemographic and drug-use related covariates. Transitionally housed and on-the-street homeless subjects made up 16% of the total sample. On-the-street homeless IDUs were more likely to test positive for HIV than were transitionally housed and housed IDUs. In the adjusted analysis, on-the-street homeless subjects were significantly more likely to share needles, share rinse water, and practice back loading than the other two groups. Sexual risk behaviors (last 30 days) were not significantly associated with residential status after adjustment. Findings from this study present an added challenge to drug treatment and HIV prevention and treatment programs, to provide services that can address the additional needs of drug users suffering the stressors of homelessness.
