General Thermography

Cellulitis is a bacterial skin infection in which the skin appears red, warm, swollen, and painful to the touch. Ascending lymphangitis may also be present. Streptococci or staphylococci are the most likely causes. Severe cases of bacterial cellulitis can produce tissue damage, necrosis, disseminated infection, septic shock, and death. Nearly one in every three diagnoses of bacterial cellulitis is incorrect, however, resulting in the misuse of antibiotics.29 Cellulitis must be differentiated from pseudocellulitis.30 Since localized skin warmth is a characteristic feature of true cellulitis, thermography may help differentiate these conditions.

Cellulitis is acute inflammation of the skin and subcutaneous tissues. It presents as swelling and erythema to the affected area and may or may not be associated with a collection (Figure 3.2). Try to establish how rapidly the erythema is spreading and check for associated lymphangitis (inflammation or infection of the lymphatic system) as evidenced by red lines running up the arm. If there is a visible/palpable collection of pus, this needs to be drained as previously described (Figure 3.3). Rapid spread of cellulitis, the presence of lymphangitis, abnormal blood results or abnormal observations (e.g. fever/tachycardia) in the context of cellulitis are indications to admit for intravenous antibiotics and close monitoring.
Botulinum toxin complications and management

Your patient will likely present with an area of hot, red and exquisitely tender skin. The afflicted area will likely look tight and shiny, with or without overlying dry patches. Should the cellulitis be inadequately treated, then tissues will become indurated and firmer to the touch as the infection progresses.
Late-onset Vibrio vulnificus septicemia without cirrhosis

Foodborne V. vulnificus illness often initially manifests as gastroenteritis; exam characteristically reveals hemorrhagic bullae.10 Dissemination across gastrointestinal mucosa occurs days later, producing a primary septicemia.11–13 Our patient’s course fit the description but with an unusually prolonged incubation time (1.5 weeks versus 1–3 days). In contrast, wound-exposure infections often fare better. Complications include necrotizing fasciitis or secondary septicemia following primary cellulitis.14,15 In susceptible populations, like people with diabetes, acquisition may occur without obvious skin ulcerations.16 Differences aside, both transmission routes usually feature symptoms peaking within days of exposure.10,12,14,17
Reduced antibiotic prescription rates following physician-targeted interventions in a dental practice

The principles for prescribing antibiotics are taught in dental schools but have been largely ignored in dental clinics for various reasons. There are four general indications in principles of antibiotic prescriptions [7,8]. First, the severity of infection at the time of admission should be determined, and antibiotics should be prescribed when there is severe swelling or unidentified cellulitis. Second, if it is not possible to extract an infected tooth immediately, antibiotics should be prescribed to control the infection. Third, antibiotics should be prescribed when the patient's immune response is weakened. Fourth, antibiotic prophylaxis can be used in an attempt to prevent complications even in immune competent individuals. Antibiotics used for these cases should have narrow spectrums, have low side effects, and be administered in appropriate doses.
Outpatient therapeutic paracentesis for malignant ascites: A short report reviewing local practice that supports procedural safety

None of the complications recorded was life threatening with the commonest complication being that of post-paracentesis fluid leakage (3.3% of the procedures). This complication is more frequently associated with tunnelled catheters rather than paracentesis as suggested by Stukan12 who noted zero cases in 275 patients who underwent the latter. The relatively larger calibre of the needle used may be one explanation. A fluid leak is easily managed in this patient group using a small adhesive ostomy bag. Rather than gauze dressings alone, which can rapidly become soaked, necessitating repeated dressing change, and risk development of skin maceration. The leakage generally resolves within 24–48 h. The two cases of cellulitis resolved with oral antibiotics course within 7 days.
