Luteoma of Pregnancy Presenting with Severe Maternal Virilisation: A Case Report.

Luteoma of pregnancy is a rare, benign condition characterized by a tumor-like mass of the ovary that emerges during pregnancy and regresses spontaneously after delivery. It is usually asymptomatic and the diagnosis is generally incidental. Luteoma arises from the proliferation of luteinised cell under the influence of ß-hCG and can be hormonally active, with production of androgens resulting in maternal and fetal hirsutism and virilisation. We report a case of a 25-year-old primigravida who presented at 28 weeks of gestation with virilisation symptoms. Serum androgen levels were seven-hundred-fold higher than normal. A diagnosis of pregnancy luteoma was made at the time of caesarean section. The ovarian mass, serum androgen levels, and the condition of the patient improved after delivery.

The Pacman Perforator-Based V-Y Advancement Flap for Reconstruction of Pressure Sores at Different Locations.

BACKGROUND: Many procedures have been proposed for the treatment of pressure sores, and V-Y advancement flaps are widely used to repair a defect. Unfortunately, the degree of mobility of a V-Y advancement flap is dependent on the laxity of the underlying subcutaneous tissue. This is an important disadvantage of traditional V-Y advancement flap and limits its use.We used V-Y advancement flaps as perforator-based to overcome mobility restriction problem, with a further modification (Pacman-like shape) to improve the covering surface area of the flap. METHODS: Between January 2012 and December 2014, the authors used 37 V-Y Pacman perforator-based flaps in 33 consecutive patients for coverage of defects located at sacral (n = 21), ischial (n = 13), trochanter (n = 1) regions. There were 27 male and 6 female patients with a mean age of 49.9 years (range, 15-74 years). RESULTS: All flaps survived completely (92.3%) except 3 in which one of them had undergone total necrosis due to hematoma and the other 2 had partial necrosis. No venous congestion was observed. The mean follow-up period was 14.9 months (range, 2-38 months). No flap surgery-related mortality or recurrence of pressure sores was noted. CONCLUSIONS: The V-Y Pacman perforator-based advancement flaps are safe and very effective for reconstruction of pressure sores at various regions. The advantage of our modification procedure include shorter operative time, lesser pedicle dissection, low donor site morbidity, good preservation of muscle, and offers remarkable excursion to the V-Y flap, which make the V-Y Pacman perforator-based flaps an excellent choice for large pressure sore coverage.

Inferiorly based parenchymal flap mammaplasty: a safe, reliable, and versatile technique for breast reduction and mastopexy.

BACKGROUND: Breast reduction and mastopexy are among the most frequent procedures in aesthetic breast surgery. Many approaches have been described, and various types of dermaglandular pedicles for the nipple-areola complex have been used. The authors present a technique suitable for either mastopexy or breast reduction whereby the superior or superomedial pedicle supplying the nipple-areola complex is combined with an inferior dermaglandular flap to restore the upper pole fullness, thereby improving breast shape and projection. METHODS: From January of 2008 to January of 2010, 83 patients underwent inferiorly based parenchymal flap mammaplasty. Patients' ages ranged from 23 to 65 years. The mean follow-up period was 27 months. The inferior breast tissue that is usually removed in a superior/superomedial pedicle technique is spared and shaped as a small implant and stitched to the pectoralis major muscle. The superior/superomedial pedicle is used for the nipple-areola complex. RESULTS: All the procedures were successful. No major complications were reported. All the patients were very satisfied with the shape, size, projection, and upper pole fullness of their breast postoperatively as reported by the questionnaire. Comparative evaluation test scores of a four-member jury were significantly higher regarding breast shape (p = 0.007), projection (p = 0.0041), and upper pole fullness (p = 0.0028). CONCLUSIONS: The inferiorly based parenchymal flap mammaplasty is a safe, versatile, and reproducible technique. It demonstrates ease of pedicle shaping and breast remodeling in patients undergoing mastopexy and breast reduction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Current indications for and comparative analysis of three different types of latissimus dorsi flaps.

BACKGROUND: Free tissue transfer with lower abdominal flaps for autologous breast reconstruction is not suitable for all patients. The latissimus dorsi (LD) musculocutaneous flap is an alternative, effective method for both immediate and delayed breast reconstruction. OBJECTIVES: The authors assess their experience with LD flaps for breast reconstruction, including indications for patient selection, donor site choice, aesthetic outcomes, complications, and patient satisfaction. METHODS: Charts for all patients who underwent breast reconstruction with one of three types of LD myocutaneous flaps during a three-year period at a single institution were retrospectively reviewed. Patients (n = 82) were divided into three groups: (1) 35 patients received a standard LD myocutaneous flap with implant, (2) 18 patients underwent a muscle sparing LD flap procedure with implant, and (3) 29 patients had an autologous LD flap. A questionnaire was administered to assess flap and donor site complications, aesthetic outcomes, patient satisfaction, and shoulder function. RESULTS: Flap complications occurred in 13 patients (15%). Donor site complications occurred in 24 patients (28%), mostly consisting of back seroma with the autologous LD flap. There was no significant difference in shoulder range of motion or muscle strength between the operated and unoperated sides. Patient satisfaction was high in all three study groups. CONCLUSIONS: The LD is a safe, versatile, and reproducible technique for breast reconstruction. The procedure benefits from ease of flap harvesting and setting and may provide satisfactory results in diverse patients, including those for whom an abdominal flap is neither indicated nor feasible. .

Breast reshaping with dermaglandular flaps after giant lipoma removal: versatility of oncoplastic techniques.

Lipomas of the breast are benign lesions that do not raise great interest in the literature and their incidence is unclear. They usually are small, benign soft tissue tumors of fat cells that can be treated by simple excision. Although lipoma is a banal condition, it often causes diagnostic and therapeutic uncertainty. The first reason for this is the normal fatty composition of the breast. Second, it may be difficult to distinguish a lipoma from other benign or malignant lumps. This report presents a rare case involving giant lipoma of the breast that compromised most of the mass of the breast. After resection, the remaining breast was reshaped using multiple dermaglandular flaps to restore the breast mound, and contralateral breast mammaplasty was performed for symmetry. This case is a good illustration of the oncoplastic reconstruction options available after wide local excision.

GMP-compliant culture of human hair follicle cells for encapsulation and transplantation.

Human hair follicle cells, both bulge and dermal papilla cells, were isolated and cultured in a GMP cell factory, in order to obtain an in vitro hair follicle source for encapsulation end transplantation in alopecia regenerative cell therapy. An in vitro model, constituted by organotypic cultures of human skin sample, was set up to simulate the dermal-epidermal interaction between bulge cells and dermal papilla cells, evaluating the possible new follicles formation and the regenerative potentiality of these hair follicle cells. Both the bulge and dermal papilla cells show an excellent cellular proliferation as well as an abundant extracellular matrix production. The immunofluorescence investigation revealed the positivity of both cell lines to CK15 and CD200, whereas both cell lines were negative to CD71 and Oct-4. The pool of cultured bulge and dermal papilla cells was injected into the deep dermis; at day 28 of culture, some organized areas with a higher cell density can be observed: the cells self-organize into papilla-like lengthened aggregates. In samples in which the follicular cells have been seeded on the dermis surface, an epidermis-like homogeneous monolayer on the dermis surface can be seen, therefore showing a potentiality of these cells for epidermis regeneration. These data show the efficacy of a cellular isolation and amplification approach to obtain an in vitro human hair follicle regenerative source on industrial scale in a GMP cell factory. The results also proved an intrinsic potentiality of follicular cells to in vitro recreate the epidermis for tissue engineering purposes. Thus, it is feasible to produce bioengineered hair follicles in a GMP cell factory, for encapsulation and transplantation in alopecic patients.

Successful management of deep facial burns in a patient with extensive third-degree burns: the role of a nanocrystalline silver dressing in facilitating resurfacing.

Full-thickness burns of the face are notoriously difficult to repair and their management poses a series of problems to the surgeon. We present the case of a 49-year-old man (only survivor of a catastrophic airport accident) with third-degree flame burns to >80% of total body surface area and extensive face damage who achieved a fully satisfactory outcome after a treatment plan based on gradual escharectomy followed by application of artificial dermis and, later, grafting with sheets of cultured keratinocytes. Re-epithelialisation was already visible at day 16 after admission and all facial wounds were closed by day 56, the treatment continuing on the scalp. Within 6 months of the accident, the patient had recovered functional and cosmetic features (including re-growth of skin appendages) that were beyond expectations. The use of nanocrystalline silver-coated dressings during the escharectomy and resurfacing phases was important, as part of a multifaceted strategy, in ensuring excellent antimicrobial control, thus avoiding the need for autologous grafting and contributing to a rapid healing and complete restoration of the face and head skin.

Computer-aided diagnosis of melanocytic lesions.

BACKGROUND: The clinical diagnosis of melanoma could be difficult for a general practitioner and, in some cases, for dermatologists. To enhance and support the clinical evaluation of pigmented skin lesions a computer-aided diagnosis has been introduced. MATERIALS AND METHODS: Images of melanocytic lesions (477 total, 42 melanomas and 435 melanocytic nevi) evaluated in epiluminescence microscopy and recorded with x16 magnification were selected. A training set of 22 melanomas and 218 nevi was randomized from the dataset. The test set was formed by the complement (the remaining 20 melanomas and 217 nevi). Furthermore, a set of images consisting of 31 melanomas and 103 nevi was selected to compare the discrimination capacity of three general practitioners and three dermatologists with experience in dermoscopy (2 years), and with the automatic data analysis for the melanoma early detection system (ADAM). Sensitivity and specificity were estimated for observer assessments and computer diagnosis. RESULTS: The entire dataset used to test the implementation of the diagnostic algorithms ADAM showed a good sensitivity and specificity performance. Compared with the physicians, the ADAM system showed a slightly higher diagnostic performance in terms of sensitivity and a lower one in terms of specificity. Dermatologists showed higher levels of specificity, but lower levels in terms of sensitivity, when compared with the general practitioners. CONCLUSION: Image analysis has the potential to distinguish nevi and melanomas and to support the clinical diagnosis of melanocytic lesions by the general practitioner.

Repetitive transcranial magnetic stimulation in schizophrenic patients reporting auditory hallucinations.

Auditory hallucinations are experienced by 60-80% of person with schizophrenia and can often cause significant distress behavioural dyscontrol. The application of rTMS in the left temporoparietal cortex could modulate the neuronal activation and reduce the occurrence of auditory disperceptions. Sixteen schizophrenic patients (treated with atypical antipsycothic drugs) reporting auditory hallucinations were included in the study. Low frequency rTMS (1 Hz) was performed at the 90% of resting motor threshold (MT), during 4 sessions in four consecutive days for 15 minutes each application. Eight patients received active stimulation, while eight patients received sham stimulation. Scale for the assessment of positive symptoms (SAPS), scale for the assessment of negative symptoms (SANS) and a scale to asses the severity of the auditory hallucinations (SAH) were administered at the beginning and at regular intervals during the follow-up. The present study confirms the reduction in auditory hallucinations by means of rTMS. The main finding was the long-term reduction in auditory hallucinations in the active group, with a return to the baseline in the sham group. The negative symptomatology improved only in the later sessions and lasted during the follow-up. The improvements in auditory hallucinations and positive symptomatology increased and lasted during the follow-up till the end-point. These data suggest that this approach may lead to an alternative somatic intervention for auditory hallucination in patients with schizophrenia.
