background pilonidal disease is a common condition that affects younger people in which over half of the affected patients present with a sacrococcygeal abscess. this study was performed to compare the outcome of excision and primary closure with that of rhomboid excision and flap procedure in patients with uncomplicated pilo­nidal disease. methods a total of 90 consecutive patients with piloni...

PURPOSE We investigated the best position for shoulder retractor strengthening exercise to maximize middle trapezius activity and minimize rhomboid major activity. Although both trapezius and rhomboids are scapular retractors, rhomboids also act as downward rotators of the scapula, which can worsen subacromial impingement. METHODS Twelve healthy participants (age 30 [SD 6] y) with no history ...

OBJECTIVE This prospective study aimed to evaluate dimensions of sacral rhomboid (quadrangular area at lower back) as predictors of Contracted pelvis (CP). METHODS In 300 uncomplicated primigravidae after 37 weeks gestation, transverse and vertical diagonal (TD and VD) of sacral rhomboid were recorded. Post- delivery, patients fell into two groups: Normal Deliveries (group 1) and CP (group 2,...

Sprain of the costoclavicular (rhomboid) ligament is an uncommon but symptomatic traumatic injury. To date, there is no report of the MRI findings of isolated, traumatic, rhomboid ligament injury. We report a case of traumatic rhomboid ligament avulsion from the clavicular insertion diagnosed by MRI. Radiologists and treating physicians alike may find this information useful in their clinical p...

Rhomboid proteases are membrane-embedded enzymes conserved in all kingdoms of life, but their cellular functions across evolution are largely unknown. Prior work has uncovered a role for rhomboid enzymes in host cell invasion by malaria and related intracellular parasites, but this is unlikely to be a widespread function, even in pathogens, since rhomboid proteases are also conserved in unrelat...

Color vision is based on the differential color sensitivity of retinal photoreceptors, however the developmental programs that control photoreceptor cell differentiation and specify color sensitivity are poorly understood. In Drosophila there is growing evidence that the color sensitivity of the R8 cell within an individual ommatidium is regulated by an inductive signal from the adjacent R7 cel...

Rhomboid peptidases are members of a family of regulated intramembrane peptidases that cleave the transmembrane segments of integral membrane proteins. Rhomboid peptidases have been shown to play a major role in developmental processes in Drosophila and in mitochondrial maintenance in yeast. Most recently, the function of rhomboid peptidases has been directly linked to apoptosis. We have solved...
