Hyperpigmentation in pregnancy is a common phenomenon, experienced to some degree by up to 90% of pregnant women. It mainly involves sun-exposed areas, but it can extend to non-exposed zones. Cases with extensive hyperpigmentation are rarely reported. In this paper, we describe the case of a 30-year-old phototype V woman in her 37th week of pregnancy, who presented with brownish hyperpigmentation of the skin in extensive areas, including both axillae, the abdomen, and the lowest part of the back. In the abdomen, there was a reinforcement of the hyperpigmentation through the linea nigra and the umbilicus...

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is a cutaneous drug reaction characterized by erythema over the buttocks, thighs, groin, and flexural regions most commonly associated with the use of beta-lactam antibiotics. Although the exact pathophysiology of this disease remains unknown, it is theorized to be the result of a delayed hypersensitivity response presenting as a cutaneous eruption days to weeks after exposure to the drug. The treatment involves discontinuation of the suspected medication, symptomatic control of pruritus, and topical steroid therapy...

Phakomatosis pigmentovascularis (PPV) is a syndrome characterized by the association of a vascular nevus with a congenital pigmented lesion (epidermal nevus, nevus spilus, and dermal melanocytosis). There are different types of PPV according to the pigmentary nevus associated with the vascular malformation. Patients may present only the cutaneous condition or have systemic manifestations, among them, trauma, neurological and ophthalmological disorders. We report the case of a 1-year-old girl who had congenital glaucoma...

Radiation therapy is used in the management of a number of childhood cancers and can have significant effects on skeletal growth. We present the case of a 35-year-old woman who developed a hypoplastic pelvis and buttocks following radiotherapy for rhabdomyosarcoma of the vagina at the age of 2. At the age of 25, the patient underwent bilateral buttock augmentation with a two-stage reconstruction using tissue expansion followed by definitive augmentation with anatomical breast implant insertion. The patient continues to have a satisfactory outcome 10 years following reconstruction, having undergone a single uplift procedure and exchange of implants through the original incision 9 years postoperatively...

The objective of the present study was to clarify the variation in and properties of mental images and policies used to regulate specific image selection when learning to control a brain-computer interface. Healthy volunteers performed a reaching task with a virtually generated monkey tail-like object on a computer monitor by regulating event-related desynchronization (ERD) on the buttock area of the sensorimotor cortex as recorded by electroencephalogram (EEG). Participants were instructed to find a free image by which the tail was well controlled...

BACKGROUND: Transcutaneous oxygen pressure (tcpO2) reliability is blunted by an unpredictable transcutaneous gradient through the skin. We hypothesized that the "Decrease from Rest of Oxygen pressure (DROP: subtraction of limb-changes from chest-changes from the respective starting values) would show a good to excellent reliability during Exercise -tcpO2 investigations. METHODS: In three different experiments we tested: The intra-test variability at the peripheral level (Experiment A: 32 patients, 16 at each location), at the chest level (Experiment B: 45 patients) and the test-retest reproducibility within 3 months (Experiment C: 67 patients)...

CONTEXT: Lumbar foraminal stenosis is often seen in patients with lumbar spine disease; however, its diagnosis is often difficult, both by physical examination and in terms of imaging. We focused on leg pain in a sitting position and defined a positive result more specifically as, "impossible to sit still and straight on the chair for about 3 minutes due to the appearance of lower limb pain or buttock pain," and we named this the "Three-Minute Sitting Test" (TMST). FINDINGS: Nineteen (7...

V an Neck-Odelberg disease (VND) is a benign skeletal overgrowth of the ischiopubic synchondrosis (IPS) in prepubescent patients. There is a paucity of long-term follow-up data and reviews on management decision-making. We report on a 15-year-old female, with a history of sickle-cell disease (HbSS), presenting with unilateral groin pain. Patient's physical examination, radiographs, and a literature-review determined a diagnosis of VND. Conservative treatment was issued. Clinical symptoms resolved at three months, followed by complete lesion resolution at three years...

Giant congenital melanocytic nevi may be symptomatically isolated, or syndromic. Associations with capillary malformations are exceptional, and development of epidermal cysts has not been described. A 71-year old patient with a giant congenital melanocytic nevus of the lower back, buttocks and thighs was asymptomatic except for unexpected hemorrhage during partial surgical excision years before. Blunt trauma at age 64 initiated recurrent, severe pain under the nevus; multiple large epidermal cysts then developed within it...

We explored use of the suction-blister wound model in the assessment of not only epidermal regeneration but also pain, the microvascular response and bacteriology. The effects of topical zinc sulfate were studied to articulate the methodologies in this double-blind trial. One epidermal suction blister (10 mm) was induced on each buttock in 30 healthy volunteers (15 females:15 males) and de-roofed on day 0. The wounds were randomized to daily treatment with 1.4% zinc sulfate shower gel (n = 20), placebo (n = 20) or control (n = 20)...

Proximal hamstring injuries cause buttock pain and may result in significant weakness and sciatic neuralgia. Avulsion ruptures involving 2 or more tendons with >2-cm retraction may benefit from early open surgical repair. More chronic equivalents may benefit from Achilles allograft reconstruction. Chronic proximal hamstring syndrome causing posterior thigh and sit pain may occur from less severe, often repetitive injury to the proximal hamstring origin with secondary sciatic neuralgia from local adhesions or scar entrapment...

INTRODUCTION: Tumoral calcinosis is a rare benign disease, defined by the presence of calcified deposits in periarticular tissues. It can be hereditary or secondary at chronic renal failure at the stage of dialysis. This work illustrates the contribution of single-photon emission computed tomography (SPECT/CT) in the diagnosis and management of tumoral calcinoses in a chronic hemodialysis patient, based on a clinical case. CASE REPORT: A 62-year-old patient, chronic hemodialysis since 24 years, presented a mechanical pain shoulders, knees and hips with limitation of joint mobility...

CASE: A 65-year-old man with a completely transected left sciatic nerve at the buttock received an implant with a bioabsorbable nerve conduit over a 20-mm gap. The conduit was filled with collagen to facilitate nerve regeneration. At 4 years after implantation, reinnervation potentials were detected in the muscles, and there was sensory recovery in the reinnervated areas. Thereafter, motor and sensory function recovered gradually over a 14-year period. CONCLUSION: Mixed nerve regeneration after conduit-based reconstruction was demonstrated objectively...
