Assessing associations between insecure income and US workers' health: An IPUMS-MEPS analysis.

Gig economy compensation policy initiatives, such as California Prop 22, are increasing the number of US workers receiving piece rate pay (PRP) and other forms of insecure income. However, there is limited evidence about how this trend affects people's health. Using data from the 2008-19 IPUMS Medical Expenditure Panel Survey (MEPS), we examined associations between insecure compensation and US adults' self-reported overall health as well as psychological distress. We report significant associations with three types of insecure income - PRP, hourly, and daily pay - on overall health and psychological distress. These effects were robust to adjustment for suspected confounders, but point estimates suggested that the effect of each type of non-salary compensation differed by sex, level of education, income level, and health insurance coverage. These findings warrant policy makers' consideration as they balance the purported benefits of gig economy non-salary compensated work with implications for workers' health.

Fibula free flaps: the role of angiography in patients with abnormal results on preoperative color flow Doppler studies.

BACKGROUND: The reliability of normal color flow Doppler (CFD) study results in predicting the safety of fibula free flap harvest has been recognized. The significance of abnormal CFD study results when used for preoperative assessment of a potential fibula free flap donor site is less well defined. OBJECTIVE: To determine if abnormal preoperative CFD study results should exclude fibula free flap harvest or if patients, in whom the fibula free flap is thought to be the best reconstructive option, should undergo further evaluation with angiography to better determine fibula free flap candidacy. METHODS: A retrospective review identified 17 potential fibula free flap candidates (34 legs) evaluated by both a lower extremity CFD study and a lower extremity angiogram. The results of the CFD study were then compared with those of angiography. RESULTS: There were 16 legs with normal CFD study results and subsequent angiographic findings confirming the safety of each of these legs for fibula free flap harvest. There were 18 legs that demonstrated abnormal CFD study results. Angiography revealed anatomy that was considered to represent a high risk for fibula free flap harvest in 16 legs and considered safe in the other 2 legs. All 14 legs that had at least 1 vessel with a monophasic waveform or no flow on the CFD study revealed a high-risk angiogram result. Of the 4 legs with biphasic waveforms in all trifurcation vessels on the CFD study, 2 revealed angiogram results that showed that they were safe for flap harvest. CONCLUSIONS: Preoperative CFD studies that reveal a monophasic waveform or absence of flow accurately identify unsafe donor sites. Fibula free flap harvest in these cases can be excluded based on abnormal CFD study results alone, eliminating the need to perform angiography.

Management of the orbital floor in silent sinus syndrome.

BACKGROUND: Enophthalmos in a patient with an opacified hypoplastic maxillary sinus, without sinus symptomatology, describes the silent sinus syndrome. A current trend is to perform endoscopic maxillary antrostomy and orbital floor reconstruction as a single-staged operation. A two-staged approach is performed at our institution to avoid placement of an orbital floor implant in the midst of potential infection and allow for the possibility that enophthalmos and global ptosis may resolve with endoscopic antrostomy alone, obviating the need for orbital floor reconstruction. METHODS: A retrospective review identified four patients with silent sinus syndrome evaluated between June 1999 and August 2001. Patients presented to our ophthalmology department with ocular asymmetry, and computerized tomography (CT) scanning confirmed the diagnosis in each case. RESULTS: There were three men and one woman, with ages ranging from 27 to 40 years. All patients underwent endoscopic maxillary antrostomy. Preoperative enophthalmos determined by Hertel's measurements ranged from 3 to 4 mm. After endoscopic maxillary antrostomy, the range of reduction in enophthalmos was 1-2 mm. Case 2 had a preoperative CT scan and a CT scan 9 months after left endoscopic maxillary antrostomy. Volumetric analysis of the left maxillary sinus revealed a preoperative volume of 16.85 +/- 0.06 cm3 and a postoperative volume of 19.56 +/- 0.07 cm3. This represented a 16% increase in maxillary sinus volume postoperatively. Orbital floor augmentation was avoided in two patients because of satisfactory improvement in enophthalmos. In the other two patients, orbital reconstruction was performed as a second-stage procedure. There were no complications. CONCLUSION: Orbital floor augmentation can be offered as a second-stage procedure for patients with silent sinus syndrome. Some patients' enophthalmos may improve with endoscopic antrostomy alone.

The transcaruncular approach to the medial orbital wall.

OBJECTIVE: To demonstrate the safety and use of the transcaruncular approach as a surgical technique that provides rapid exposure of the medial orbital wall and apex through a small cosmetic conjunctival incision. METHODS: The transcaruncular anterior orbitotomy incision is made through the conjunctiva, between the plica and caruncle, with dissection to a subperiorbital plane along the medial orbital wall. This technique was used in 49 patients (58 orbits) between July 1995 and December 2000. The patients' ages ranged from 5 to 89 years (mean, 50 y). RESULTS: The transcaruncular anterior orbitotomy approach provided appropriate surgical exposure in all cases of orbital decompression for thyroid-related orbitopathy (in 33 orbits [26 patients]); for biopsy of medial orbital or orbital apex masses in 12 patients; and for drainage of an orbital abscess or marsupialization of a mucocele in 7 orbits (6 patients). Five patients (6 orbits) underwent a transcaruncular approach for release of medial rectus entrapment after fracture. The single complication was 1 patient who required a revision procedure for treatment of medial fornix scarring with resolution of diplopia. CONCLUSIONS: The transcaruncular approach provides a safe, rapid, and cosmetically pleasing surgical approach to the medial orbital wall and orbital apex. This technique can be used for a variety of indications.
