Purpose  

To compare patients over 70 years old with those under 50 years old undergoing inguinal hernia repair.     

Resection of extrahepatic hepatocellular carcinoma metastasis can result in long-term survival

Hepatocellular carcinoma (HCC) is one of the most common primary cancers in the world and the third most common cause of cancer mortality world-wide. Surgery is the gold standard in the treatment of patients with HCC. The prognosis is mainly determined by the underlying liver disease and recurrent rates. In the Western World, up to 30% of the patients with HCC have a non-cirrhotic liver. The main prognostic factor in this special group of patients are the recurrences. Most recurrences are intrahepatic; however, 30% of the recurrences are extrahepatic. The role of resection in case of intrahepatic recurrences is widely accepted, particularly in the non-cirrhotic liver. The role of resection in extrahepatic HCC recurrences is not well established and unknown among many physicians. We present two patients with HCC in a non-cirrhotic liver with extrahepatic recurrences and long-term survival after resection. The corresponding literature support an aggressive approach in case of extrahepatic HCC recurrence in selected cases: resectable metastasis, preserved liver function, absence of intracranial metastasis and control of the primary tumour. Further research is warranted because of the limited number of reports and the absence of randomized trials.     

Squamous cell carcinoma lower lip - an experience with Karapandzic technique

Carcinoma of the lip is a common cancer of head and neck area. It occurs frequently on the lower lip of middle-aged and elderly males who have a history of chronic sun exposure. Surgical excision and radiotherapy are regarded as equally effective treatment options, but preferred method is surgical excision. Karapandzic technique provides myoneurovascular pedicled advancement flap for reconstruction of the defect after surgical excision. It is a simple and safe technique, functionally and esthetically, sacrifices little tissue, heals rapidly and is effective for repair of defects covering 1/3 to 4/5 of the lower lip. We report a 62 years male who presented with a large, fungating, pus-discharging and tender mass of lower lip. Biopsy confirmed squamous cell carcinoma. Tumor was excised and defect was reconstructed using Karapandzic technique. Patient remained asymptomatic during follow-up visits.     

The current role of the artificial urinary sphincter for the treatment of urinary incontinence

PURPOSE: The introduction of the artificial urinary sphincter (AUS) in 1972 was heralded as a revolution for the treatment of genuine stress incontinence. Initial enthusiasm was tempered by disappointment as complications occurred. The device has now been in routine clinical use for more than 30 years, and the indications and surgical principles involved in its use along with short-term and long-term outcomes are more clearly defined. Hence, we reviewed the literature to clarify the role of the AUS and offer a possible solution to its problems in the guise of a new sphincter. MATERIALS AND METHODS: A MEDLINE search was performed and all articles relating to the role of the AUS for the treatment of urinary incontinence were reviewed. RESULTS: The AMS 800 (American Medical Systems, Minnetonka, Minnesota) provides urinary continence in 73% of cases (range 61% to 96%) and it has a complication rate of 12% (range 3% to 33%) for mechanical failure, 4.5% to 67% for early infection/erosion, 15% for late erosion and 7% for delayed recurrent incontinence. The literature supports the role of the AUS as an important and reliable treatment modality for stress urinary incontinence and intrinsic sphincter deficiency. However, it is not suitable in all patients and its use for the management of hypermobility is controversial. Hence, careful patient selection according to indication is required with full preoperative counseling. CONCLUSIONS: Despite its reliability for achieving urinary continence the AMS 800 is not perfect. Newer devices, such as that being developed at our institution, may offer improved outcomes and decreased complication rates.     

Bacterial biofilm and associated infections

Microscopic entities, microorganisms that drastically affect human health need to be thoroughly investigated. A biofilm is an architectural colony of microorganisms, within a matrix of extracellular polymeric substance that they produce. Biofilm contains microbial cells adherent to one-another and to a static surface (living or non-living). Bacterial biofilms are usually pathogenic in nature and can cause nosocomial infections. The National Institutes of Health (NIH) revealed that among all microbial and chronic infections, 65% and 80%, respectively, are associated with biofilm formation. The process of biofilm formation consists of many steps, starting with attachment to a living or non-living surface that will lead to formation of micro-colony, giving rise to three-dimensional structures and ending up, after maturation, with detachment. During formation of biofilm several species of bacteria communicate with one another, employing quorum sensing. In general, bacterial biofilms show resistance against human immune system, as well as against antibiotics. Health related concerns speak loud due to the biofilm potential to cause diseases, utilizing both device-related and non-device-related infections. In summary, the understanding of bacterial biofilm is important to manage and/or to eradicate biofilm-related diseases. The current review is, therefore, an effort to encompass the current concepts in biofilm formation and its implications in human health and disease.
