Fournier's Gangrene: A Case Study

1495 Words6 Pages

INTRODUCTION

Fournier’s gangrene is a rare, rapidly progressive, fulminant form of necrotizing fascitis of the genital, perianal and perineal regions.1 It is characterised by progressive spread of necrosis in the skin and subcutaneous tissue combined with severe systemic infections.2 It is a polymicrobial infection and is caused by both aerobic and anaerobic bacteria which further leads to thrombosis of subcuatneous and subcutaneous blood vessels, resulting in severe gangrene.3 Any trauma or infection in the perineal region or urinary tract forms the initial focus of disease.4 In general, the infection occurs in immunocompromised patients such as diabetic, HIV seropositive, alcoholic and elderly individuals. Patients who are undernourished and from low socioeconomic strata are …show more content…

Anatomical basis of the flap

The medial thigh flap is based on septocutaneous branch of femoral artery. The axis of the flap is a line joining the apex of the femoral triangle and the medial femoral condyle. The skin territory of the flap extends from the inferior aspect of the femoral triangle to the junction of the middle and distal thirds of the medial thigh. The lateral edge of adductor longus and the medial edge of rectus femoris muscle makes the lateral border of flap.12

Surgical technique

All patients were operated under general anaesthesia with orotracheal intubation in lithotomy position. The axis of the flap was a line joining apex of femoral triangle to the medial femoral condyle. The dominant pedicle was located at the apex of the femoral triangle around 6-8 cm below the inguinal ligament and it was detected preoperatively by Doppler examination. The width of the flap ranged from 7-11 cm whereas the length ranged from 15-25 cm. Dissection was done distal to proximal in the subfascial distal plane over the muscle. After harvesting flap was rotated to cover the testicular and perineal area and creating a scrotum with tension free

No previous medical history and there are no known allergies. Terrance had a skateboarding accident where there were multiple lacerations and contusions. The wound on his forearm extending to his elbow was slow healing and therefore became pus producing. The patient has since returned to his primary care physician to find out what is going on.

    It is important to discuss these options with your veterinarian and have your animal seen regularly as well as keeping your pet at a healthy weight. It is worth noting that on a general basis a luxation at grade 1 does not necessitate surgery, grade II could benefit from surgery depending on wear/pain and inflammation of the knee, and grade III and IV necessitate surgery. Annex 4: Umbilical Hernia An umbilical hernia is an undesired communication between the interior of the abdomen and the area bellow the skin (subcutaneous) in the area of the umbilicus (belly button). This communication is due to the fact that the muscle wall of the animal did not close completely after the mother cut the umbilical cord at birth.

    There was a high probability the bacterial infection could have been necrotizing fasciitis due to the overlapping signs and symptoms of both infections. Both of these bacterial infections can be caused by a Gram-positive bacteria called Clostridium perfringens and the portal of entry for this endospore is through breaks in the skin that will infect the tissue. Necrotizing fasciitis causes intense pain and swelling at the site of infection. Discoloration of the skin along with hot to the tough, fever, nausea, malaise and other flulike symptoms. Patients normally have extremely low blood pressure which results in confusion.

    I am working as a GP in a polyclinic situated in Jubail,KSA.Most of the patients attending here have a place with low financial status. I am discussing a case of cellulitis which fits the course of module and an incessant conference when all is said in done practice. I picked this case since cellulitis , as I would see it, shows a few difficulties as far as differential diagnosis and fitting treatment. My point in doing this contextual case study would be to basically assess my management of cellulitis and draw some learning focuses. The case is of cellulitis of the legs, which is the one we see all the more much of the time in primary care.

    Aureus is by analyzing the damaged tissue. Skin infections associated with S. Aureus usually result in Furuncles and Carbuncles, which are boils/lesions filled with abscess. Another skin infection caused by S. Aureus is Staphylococcal scalded skin syndrome (SSSS) which peels the skin’s stratum granulosum layer off causing desquamation. This is due to the toxins ability to hydrolyze desmoglein 1 which holds the keratinocytes together and the absence of desmoglein 3 in granulosum layer. The effects are red bright skin.

    In addition, this procedure can be performed in two ways: posterior and anterior approaches. The posterior hip replacement is the traditional procedure in repairing the hip joint. For this technique, the surgeon would make a curved incision on the side of the hip on the gluteal muscles. For the other procedure, the anterior hip replacement, a surgeon would have to maneuver between the muscle to gain access to the hip joint through the front part of the hip (Kruse). The main difference between the two approaches is how the surgeon opens the body to reach the hip.

    The resected femoral head demonstrated a flattened widespread surface with a flap of articular cartilage and subchondral bone, and the cut section showed a subchondral fracture line parallel to the articular surface (Figure 4A). Histological examination showed repair tissue comprising of marked fracture callus and vascular rich granulation tissue on both sides of the fracture line (Figure 4B). There was no evidence of antecedent osteonecrosis. Histopathologic findings demonstrated that the collapse of his femoral head was caused by a subchondral fracture resulting from acetabular fracture. Figure 4 Histological findings show a subchondral fracture of the femoral head and no evidence of antecedent osteonecrosis.

    It all began in back in 1860 where the first knee arthroplasty was performed with German surgeon Thermistocles Gluck implanting the first primitive hinge joints made of ivory, which is material made out of the tusks of elephants. Obviously this became a detrimental factor to society as we can’t resort to killing elephants anymore. So this was the only presumed surgical knee reconstructions that were undertaken, until 1951 where the Walldius hinge joint was introduced for knee replacements made out of acrylic however it was later discovered that this material can cause tumors within your knee due to the expansive ability of granuloma particles. It was from 1969 where the modern total condylar knee was discovered by John Insall, chief of the Hospital of special surgery knee clinic. The total condylar was the first implant to address all aspects of the knee with anatomically shaped parts.
