Variable pH values for skin have been reported in the literature, all within the acidic range, varying from 4.0 up to 7. 0. The origin of the acidic pH remains conjectural, and several factors have been incriminated with this role, such as eccrine and sebaceous secretions as well as proton pumps. Keeping low levels of pH prevents microbial dispersal as well as multiplication. The skin in the external auditory canal is also covered with this acidic mantle with antimicrobial value. Changes of pH in the external ear can lead to acute otitis externa. This condition is defined by the inflammation and infection of the cutaneous and subcutaneous tissues of the external auditory canal. 10% of the world�s population may suffer from acute otitis externa at least once in their lifetime. This paper aims to consolidate the relevance of an acidic pH in the healthy external ear and its relation to the pathogenesis and treatment of otitis externa through a prospective and interventional clinical study on 80 patients who presented to the outpatient department at Prof. Dr D. Hociota ENT Institute in Buch

Introduction: Scar treatments aim to address pathologic collagen deposition; however, they can be expensive or difficult to control. Electrochemical therapy (ECT) offers a simple alternative treatment. The purpose of this study is to examine the acid-base and histological changes in ex vivo human abdominal skin following ECT. Methods: Forty-two ex vivo human panniculus tissue sections collected from six individuals were tumesced with normal saline. ECT was performed by inserting two platinum needle electrodes connected to a DC power supply into each specimen. Voltage was varied (3–6 V) and applied for 5 minutes. Each specimen was sectioned across both electrode insertion sites and immediately stained with pH sensitive dye. The width of dye color change for each dosimetry pair was calculated. Hematoxylin and eosin staining was used to evaluate samples. Results and Discussion: ECT caused a spatially localised and dose-dependent increased area of acidic and basic pH around the anode and cathode, respectively. A significantly greater mean width of pH change was generated at the cathode compared to the anode in all treatment groups. Histological evaluation displayed broad condensation and hyalinisation of dermal collagen. Conclusion: ECT triggered dermal pH alterations and changed the underlying structural framework of the specimen. This technology may serve as a low-cost, minimally invasive local soft-tissue remodeling technique with potential application in scar management. Level of Evidence: 5 Lay Summary Electrochemical therapy is a novel treatment that causes spatially selective dermal injury in areas of interest. This study measures the effects of electrochemical therapy when applied to abdominal skin. Electrochemical therapy appears to have beneficial effects by causing a highly localised reduction in collagen content or local softening of tissue, which is consistent with other studies on scar therapies, including chemexfoliation, radiofrequency technologies, and lasers. However, electrochemical therapy can be performed at a fraction of the costs of these aforementioned modalities.

AbstractLipomas are common benign connective tissue tumours composed of adult adipose tissue. They are relatively rare in the upper aerodigestive tract, although they occur with considerable frequency in other areas, particularly in the subcutaneous tissues of the neck. Although there are several reports of this tumour occurring in the oropharynx, there is no recorded case of a lipoma of the tonsillar fossa. An 83-year-old man with a left tonsillar fossa lipoma is presented. Clinical presentation, management and a literature review are discussed.

Between November 1993 and July 1995, 300 patients underwent penis lengthening surgery. Twelve of these patients had previous genital surgery and/or congenital anomalies, and their procedures could be considered reconstructive. The remaining surgical procedureswere cosmetic. Average patient age was 37 years (range 18 to 74 years). The average preoperative erect length was 12.5 cm (range 7.5 to 16 cm, SD 1.5). ‘Locker room phobia’, adverse female comments and body disproportion were common reasons for patients desiring surgery. All racial groups were represented, with European ancestry the most common. Surgery involved releasing all the superficial (fundiform) ligament and most of the deep suspensory ligament. The defect was filled with plicated gracilis muscle along with shifted skin and subcutaneous tissues. Postoperative traction was used to reduce the chance of scar and penis retraction. The most common major complication was wound infection (5.7%). The most frequent minor problem was dermatitis (13%). Long term (mean10months, range sixto18months) objective measurements using the stretch technique were obtained for 42 patients. One patient lost 1 cm in length, while 41 gained length (mean 3.2 cm, range 0.5 to 6 cm). Poor patient compliance with the postoperative protocol appears to be the most significant factor limiting the success of the procedure.
