The impact of the housing status on clinical outcomes and health care utilization among individuals living with HIV

ABSTRACT

The lack of stable housing can impair access and continuity of care for patients living with human immunodeficiency virus (HIV). This study investigated the relationship between housing status assessed at multiple time points and several core HIV-related outcomes within the same group of HIV patients experiencing homelessness. Patients with consistently stable housing (CSH) during the year were compared to patients who lacked CSH (non-CSH group). The study outcomes included HIV viral load (VL), CD4 counts, and health care utilization. Multivariable and propensity weighted analyses were used to assess outcomes adjusting for potential group differences. Of 208 patients, 88 (42%) had CSH and 120 (58%) were non-CSH. Patients with CSH had significantly higher proportion of VL suppression and higher mean CD4 counts. The frequency of nurse visits in the CSH group was less than a half of that in the non-CSH group. Patients with CSH were less likely to be admitted to the medical respite facility, and if admitted, their length of stay was about a half of that for the non-CSH group. Our study findings show that patients with CSH had significantly better HIV virologic control and immune status as well as improved health care utilization.     

Use of Hyaluronidase in the Treatment of Granulomatous Hyaluronic Acid Reactions or Unwanted Hyaluronic Acid Misplacement

Background. In the past, reactions or misplacement of soft tissue fillers has been fraught with anxiety because time has been the main thrust for improvement in spite of ancillary treatments. Hyaluronidase is an enzyme that dissolves hyaluronic acid in the skin and also assists in the management of granulomatous foreign-body reactions to hyaluronic acid. These reactions may be caused by allergy to the material or immunologic response to the protein contaminants in the hyaluronic acid preparations. Dissolution of material in erroneous placement of material and in allergic reactions can be a time saver and a deterrent to patient dissatisfaction.
Objective. To evaluate the use of hyaluronidase in the treatment of both allergic reactions and the erroneous misplacement of hyaluronic acid in the skin.
Methods. A case of persistent granulomatous reaction to injectable hyaluronic acid and a case of hyaluronic acid erroneous misplacement with their successful subsequent treatments using intracutaneous hyaluronidase are reported, along with illustrative examples of hyaluronidase use.
Results. The use of hyaluronidase reduced the patient discomfort within 24 to 48 hours, deterring any patient anxiety or patient dissatisfaction.
Conclusions. Hyaluronidase has a place in the treatment of allergic reactions to hyaluronidase and in the erroneous misplacement of the material.     

Relevance of Cosmeceuticals to the Dermatologic Surgeon

Background. The dermatologic surgeon is the dermatologist with special expertise in the surgical care of the health and beauty of the skin.
Objectives, Methods, Results. There is no better arena for the use of topical regimens to preserve skin quality than in the time interval devoted to before and after care with respect to surgical procedures.
Conclusion. Many of these regimens can be tailor devised with topical drugs and cosmeceuticals together in proper balance in the patient's best interest for affordable health care.

Mapping out a search for environmental causes of breast cancer.

Geographic patterns and time trends for breast cancer suggest there are preventable causes that may include environmental factors. This article describes the development of new methods used in the Cape Cod Breast Cancer and Environment Study to investigate whether synthetic chemicals in the environment contribute to breast cancer risk.     

Adult daughters and parent care: a comparison of one-, two- and three-generation households.

This paper compares the effects of parent-care associated with three living arrangements of elderly widowed mothers who were being helped by married daughters: elderly mother living separately; two-generation households (mothers, daughters, sons-in-law); and three-generation households (grandchildren present). Daughters whose mothers lived separately fared the best; their mothers were the most cognitively and functionally capable and the daughters reported the fewest negative effects of caregiving. Daughters in two-generation households provided the most care; their mothers were the oldest and most impaired. Since daughters in three-generation households reported more negative mental and emotional effects of care, the unique problems of caregiving in such households are discussed.     

Pathophysiology of congenital diaphragmatic hernia. III: Exogenous surfactant therapy for the high-risk neonate with CDH.

Exogenous surfactant therapy (EST) in surfactant-deficient premature infants has been shown to improve lung compliance, decrease morbidity, and improve survival. Reports have demonstrated that newborns with congenital diaphragmatic hernia (CDH) have lung compliance, pressure-volume curves, and hyaline membrane formation resembling those changes seen in surfactant deficient premature newborns. We hypothesize that EST may also benefit infants with CDH. All high risk cases of prenatally diagnosed CDH at Children's Hospital of Buffalo from November 1988 to February 1991 were prospectively evaluated for EST. In those families who chose to participate, the surfactant preparation, Infasurf (100 mg/kg), was instilled into the newborn's lungs prior to the first breath. The remainder of the perinatal, neonatal, and surgical care was performed in a routine manner. Three high-risk prenatally diagnosed newborns with left CDH were treated with EST. All showed signs of decreased pulmonary compliance, but could still be adequately oxygenated and ventilated. Surgical correction was performed after stabilization and all required patch closures. Two of the three infants suffered no life-threatening episodes of pulmonary hypertension and all survived. These infants had many known indicators for poor outcome in CDH with an expected survival of less than 20%. We believe that EST in these neonates with CDH contributed to their survival with minimum morbidity. These results suggest that surfactant replacement for the high-risk neonate with CDH warrants further consideration and a randomized clinical trial is being planned.     

Serratus anterior muscle transplantation for treatment of soft tissue defects in the hand

The inferior three slips of the serratus anterior muscle have been used as a free tissue transfer in 18 patients for the reconstruction of dorsal and palmar defects in the hand. Mean follow-up was 2.8 years. There were 12/18 flaps for palmar coverage and 6/18 for dorsal coverage. All flaps survived. On the basis of this experience we conclude that this flap has three attributes making it suitable for palmar and dorsal metacarpal resurfacing: (1) low donor site morbidity, (2) the three separate slips are easily divisible for contouring, and (3) durability and adhesion provide a stable resurfacing for grasp.
