Safety and efficacy of autologous noncultured dermal cell suspension transplantation in the treatment of localized facial volume loss: A pilot study

Background: Available options for correction of facial volume loss, such as synthetic fillers, autologous fat and cultured fibroblasts, have limitations viz. temporary effect and high cost. Aim: To assess the use of a novel technique, autologous non-cultured dermal cell suspension transplantation, for correction of localized facial volume loss due to inflammatory pathologies. Methods: It was a pilot study conducted in the Dermatology Outpatient Department, All India Institute of Medical Sciences (AIIMS), New Delhi, India. Autologous non-cultured dermal cell suspension was transplanted in a total of 10 patients, out of which 5 had predominantly dermal loss and the rest had predominantly lipoatrophy. The donor tissue from the gluteal region was digested into a single cell suspension using collagenase-1 and injected into the recipient area. The outcome was assessed subjectively by patients and investigators and objectively using ultrasonography. Cell count, viability testing and measurement of mesenchymal stem cells were also done. Results: On assessment of patients, the median improvement in the predominantly dermal atrophy group at 3 and 6 months was 70% (range: 10–90%) and 80% (range: 0–90%), respectively, and in the predominantly lipoatrophy group, 0% (range: 0–40) and 0% (range: 0–50), respectively. Mean thickness of dermis + subcutis at the baseline was 1.835 mm (range: 0.89–6.04 mm), which increased to 2.912 mm (range: 0.88–7.07 mm, P = 0.03) at 6 months. Limitations: Our pilot study has some limitations such as small sample size and heterogeneity of the recruited patients. Conclusions: Autologous non-cultured dermal cell suspension transplantation appears to be safe and effective in localized facial dermal defects because of inflammatory pathologies, but not effective in deeper defects.

Psychodermatology: A comprehensive review.

Psychodermatology is an interesting domain of dermatology that overlaps with psychiatry. This arena in dermatology has received limited diligence, partly due to lack of training in this realm. We present here a comprehensive review of salient features and treatment updates in primary psychiatric dermatoses and have also discussed the role of psyche in psychophysiological cutaneous disorders. Secondary psychiatric morbidity is relatively common among patients visiting the dermatologists but often overlooked and uncared for. Dermatologist should be able to initiate basic pharmacotherapy, should be knowledgeable about various non-pharmacological treatments and know the right time to refer the patient to the psychiatrist. Awareness and pertinent treatment of psychodermatological disorders among dermatologists will lead to a more holistic treatment approach and better prognosis in this unique group of patients.

Anomalous drainage of left renal vein.

A rare anatomical variation found during routine anatomical dissection for teaching purposes in which the retro aortic left renal vein opened in to the left common iliac vein instead of inferior vena cava. Retro aortic left renal vein is an uncommon anomaly in the development of Inferior Vena cava (IVC) and its collaterals. It may courses behind the abdominal aorta to enter the IVC. According to the reviewed literature, incidence of a case like this is around 0.16% and is only scarcely described in the literature. The embryological and clinical significance of the above variations have been highlighted in this communication.

Psoriasis: What is new in nonbiologic systemic therapy in the era of biologics.

Psoriasis is a common debilitating disease significantly affecting the quality of life of the patients. Majority of the psoriasis patients have mild disease which can be managed by topical therapies. Around 30% of the psoriasis patients require systemic therapy during the course of their disease. There is a vast array of drugs for the treatment. Methotrexate, cyclosporine and retinoids are the most commonly used conventional systemic drugs. Newer studies provide insight into their more effective and safer use and as combination therapy with biologics. In recent times, many new drugs with novel mechanisms of action other than biologics have been tried in psoriasis. In this article, we have reviewed the current developments and new found role of the conventional drugs as well as the newer nonbiologic systemic drugs in the treatment of psoriasis.

Proteomic analysis of heparin-binding proteins from human seminal plasma: a step towards identifi cation of molecular markers of male fertility.

Glycosaminoglycans, especially heparin, are involved in various cell processes such as apoptosis, cell cycle control, platelet activation, capacitation, acrosome reaction and sperm decondensation. Heparin-binding proteins (HBPs) are essential constituents of human seminal fl uid, which bind to sperm lipids containing the phosphorylcholine group and mediate the fertilization process. We utilized a proteomic set-up consisting of affi nity chromatography, isoelectric focusing (IEF) coupled with matrix-assisted laser desorption/ionization time-of-fl ight tandem mass spectrometry (MALDI TOF/MS) for protein analysis of human HBPs. We resolved 70 different spots on two-dimensional (2-D) gel and subsequently identifi ed these proteins. Forty different types of proteins were identifi ed. Functional analysis revealed that 38% of the proteins belonged to the enzyme category, 20% were involved in RNA processing and transcription, 18% in structure and transport function, and 16% in cell recognition and signal transduction. We also identifi ed 8% of proteins with unknown functions, although their expression in seminal fl uid has been documented. Proteins of seminal fl uid that bind heparin may be directly involved in sperm capacitation and acrosome reaction (AR), which are the two critical steps for fertilization. This information on HBPs would be useful for identifying potential biomarkers of fertility in the near future.
