Over the last few decades the once-familiar erysipelas has slippedout of the medical spotlight, while the allied disorder ofnecrotizing fasciitis or acute streptococcal gangrene has,possibly, not gained the publicity it deserves, Althougherysipelas ceased to be notifiable in 1980, it was hitherto eitherunrecognized as such, or diagnosed and treated withoutnotification, to avoid unnecessary fuss. Necrotizing fasciitis stillremains a formidable disorder, and has lost none of itsimportance through improvements in management,

Gangrene in erysipelas

The traditional view of gangrene in erysipelas is somewhatvague, but the presence of a severe infection is usually thoughtnecessary, some impairment of circulation presumed, and anelement of pressure necrosis at times implied. l Spread to thesuperficial fascia (subcutaneous fat) can then occur bydownward extension from the dermis,

This view of gangrenous erysipelas is of little service whendealing with necrotizing fasciitis, which is the primarilysubcutaneous form of acute streptococcal infection withgangrene.

Necrotizing fasciitis

Early perspectivesMeleney wrote the classic papers on haemolytic str~ptococcus

gangrene, based on his experience in Peking, China, in the early19205, to be extended later in New York.2

,3 The leading idea wasthat of a spreading subcutaneous infection, usually occurring in alimb, causing an interruption of the blood supply to theoverlying skin with a moist or dry gangrene resulting at thesurface after a couple of days. Except where the deeperstructures were damaged, as with a compound fracture, themuscle below and the deep fascia remained free from infection.Meleney pointed out that the therapeutic choice might bethought to lie between two alternatives, i.e. a conservative delayor an amputation, both of which would, in his opinion, bedisastrous mistakes. He advised instead that the necrotic fasciabe fully opened by single long incisions for drainage,debridement and relief of tension within I hour of making theclinical diagnosis.

Although haemolytic streptococcus gangrene couldcomplicate war wounds and other major injuries, it has beennoteworthy for the way it could start abruptly after quite trivialcivilian accidents within the household. In the late 19405Meleney's original views were still upheld: the dominating lesionwas always a subcutaneous necrosis with some abscessformation, and long drainage cuts were preferable to 'bearscratch' incisions.'

These complications arose from the subcutaneous accumulationof organisms and necrotic tissue under tension and undergoingconstant resorption. Moreover, the superficial fascia is, in thesecircumstances, largely impenetrable to antibiotics - hence thecontinued need for free release of infected and necrotic materialto the outside. The psychiatric aspects were also nor to beoverlooked - the clouding of consciousness and confusionalstates, apathy, and prostration, which herald death in the severecase, as well as shock.

Recent advancesOver the last decade many lesser aspects ofnecrotizing fasciitis

have been documented, though many unsolved problemsremain.

Histopathological features in the skin6 have been betterstudied. These comprise the thromboses in the microvasculatureincluding a fibrinoid arteriolitis producing tissue necrosis, theoedematous disruption of the papillary layer with subepidermalbulla formation, and the initial presence in the dermis ofIymphocyres and histiocytes only.

Microbiological features have been extended to include asynergistic action of bacterial mixtures,7 which do not requiregroup A haemolytic streptococci or aerobic staphylococci, butproduce necrotizing fasciitis through a mixture of anaerobes,other groups of streptococci, Pseudomonas, Bacleroides, etc.

Choice of antibiotics is altered as a result of the above.Benzylpenicillin and cloxacillin would be standard drugs, butmetronidazole, the aminoglycosides and cephalosporins may berequired. In diabetics the anaerobes or coliforms may bring ongas production without implying the presence of clostridia. Inhis first paper from China Meleney2 indicated that he hadobserved these bacterial mixtures, but seemed later to discounttheir importance. In passing, we may note the employment bysome of maggots or applications of honey to the wounds.

Special features of age, site and causative organisms haverepeatedly been observed. Particular differences are noted ininfants and children (with Haemophi/us or Pseudomonas as causes,needing appropriate treatment); the old-established type offulminant gangrene of the genital region described by AlfredFournier in 1883 can now also be claimed as a special type ofnecrotizing fasciitis; lesions on the trunk due to Gram-negativeorganisms are seen to be related to bowel infections and surgery,and puerperal and perineal infections occur. All these varietieshave widened the concept of necrotizing fasciitis. Anothercomplication is disseminated intravascular coagulation. Havinga decisive effect on the prognosis is the patient's general conditionin other respects - the state of the kidneys, liver, arteries, heart,general defence, metabolism, lymph flow, other drugs used, etc.,each of which bring their respective complications into thepicture and may compromise the sufferer.

Unsolved questionsEpidemic grouping. It is puzzling that in some regions and

at some times the cases occur in runs, suggesting the localemergence of strains of the group AB-haemolytic SlreplOcoccUSwith selective pathogenicity.

Microbial pathogenicity. Once inside the superficial fasciaof the host, there has been no satisfactory account of how thenecrosis and thromboses occur, apart from a general theory thatvarious toxins, Iysins, enzymes, immunological phenomena andcoagulative disturbances are responsible.

Illustrative cases

We wish to present a part of our experience with gangrenouserysipelas and necrotizing fasciitis in Pretoria through the

medium of colour pictures of representative cases. Thepredominance of elderly women in our series has made uswonder whether flabby skin tissue predisposes them in some wayto these infections.

Erysipelas of the face with gangrene of theeyelids

Fig. I. Erysipelas began at a crack in the right ear region in this47-year-old woman, and spread forward over the face from rightto left. It resulted in a haemorrhagic gangrene of the right uppereyelid, the scarring from which was later corrected by plasticsurgery.

Fig. 1.

Fig. 2. A similarly asymmetrical erysipelas of the face in a 70­year-old diabetic woman resulted in gangrene of the left upperand lower eyelids. The scarring after separation of the sloughsdid not require reconstructive surgery.

Epidermal signs in necrotizing fasciitis anderysipelas

Some uncertainty exists about epidermal detachment, bullaformation and haemorrhagic bullae in this group of diseases.

Page 3: Gangrenous fasciitis erysipelas and necrotIzIng

Fig. 3. This illustration shows an erysipelas of the leg withwidespread dermal-epidermal detachment. This detachmentresults in a loose epidermis which is crinkly amd movable overthe underlying tissue. It has the appearance of scalded skin, andcould be a prelude to haemorrhage and gangrene. It does notfollow the pattern of toxic epidermal necrolysis or thestaphylococcal scalded skin syndrome in other respects. In thispatient the condition proceeded to necrotizing fasciitis.

Fig. 3.

Fig. 4. Here an erysipelas was complicated in the later stagesby haemorrhagic bullae. In our experience such bullae are sterileand are not a prelude to gangrene, although the contrary has beenstated.

Fig. 5. This 87-year-old woman was afebrile, confused anddehydrated, with diffuse swelling of the leg, radiating patches ofgangrene on the leg and foot, and some white areas where theblack slough had come off. Blistering with apparent bruisingappeared in the groin, which progressed into a full-thicknessgangrenous slough. Later it dissected itselfloose from the deeperlayers of fat (Fig. 6). There was an uncertain history ofa fall withinjury to the leg. The gangrenous areas yielded a mixture oforganisms, including Pseudomonas aeruginosa, Pro£eus mirabilis,Escherichia coh~ and S£repr. faecalis for which the specificantibiotics were given. She died 10 weeks after admission,presumably from septicaemia, after the leg had been amputated.

Group A R-haemolytic streptococci wereisolated at first, and the surface was later complicated by ProTeusand Pseudomonas infection. After removal of the slough and skingrafting she left hospital (stay 10 weeks).

The gangrene is attended by rather litdeswelling or epidermal change, i.e. it is a dry gangrene which inposition and form may resemble the above cases fairly closely.

Skin pathology

Streptococcal necrotizing fasciitisOur biopsy material from 2 cases showed that there were two

sites for early pathological change - the dermal papillary layerand the cutis-subcutis junction. In the papillary layer, theground substance was dissolved out and the layer becameconverted into a wide and tenuous web of fibrils withhaemorrhaging into the spaces so formed. Epidermal necrosisdeveloped later. In the upper subCUTis there was acute necrotizinginflammation, with breakdown of fat cells and a thick layer ofpolymorphs lying in the subcutaneous debris. The dermis was

Fig. 15.

Fig. 16.

the last layer to alter and be filled with polymorphs, accompaniedby a necrotizing thrombosis of the superficial bloodvessels.

Gram-negative necrotizing fasciitisIn I case only, the most prominent change seen in three biopsy

specimens was the presence of red blood cells in-between theconnective tissue fibres of the dermis. In the upper dermis thered cells were fused into compact masses and me vessels werethrombosed with fibrin thrombi. These alterations wouldprobably have preceded a black gangrenous slough in the area.

Coagulation studies

Fig. 17 shows me thrombo-elastographic findings in me 2 casesillustrated in Figs 11, 12 and 13, derived from recalcified citratedwhole blood samples. These tracings demonstrate a mrombo­elastographic hypercoagulability, which was unalteredby a constant infusion of heparin (20000 V/d). In both cases thereaction time, or the rate of thromboplastin generation (me r­time) is shortened. The rapidity of fibrin build-up, or thrombinconstant (the k-time) is also shortened, while the maximalamplitude, or maximal elasticity of me fibrin clot (the ma-value)is increased.

The sum of the r-time plus the k-time equals me cloning time,and indicates the heparin tolerance. Shortened times are usuallyassociated with accelerated coagulability. An increase in me ma­value is similarly associated with a hypercoagulable state.8

Although the concept of hypercoagulability is stillcontroversial, various definitions have nevertheless been

suggested. Fisch er al. 9 define thrombo-elastographic hyper­coagulability as an accelerated rate of cloning and increasedfirmness of the formed clot. However, a hypercoagulablethrombo-elasrogram only indicates an increasedlikelihood of cloning and not acrual clot production. Thrombosisprobably requires other factors such as stasis and intimal damagebefore cloning sets in, bur the thrombelastogram enables one tomeasure a phenomenon that previously existed only in theory. 10

Discussion

Ipvestigation and managementOur cases of gangrenous erysipelas and necrotizing fasciitis in

elderly women showed a mortality and morbidity which hardlylook creditable, but which at least emphasize the seriousness ofthe condition. At the onset the disorder was sometimes difficultto recognize. An afebrile disorienrated old woman comes in, whosefamily cannot tell the nature of the alleged limb injury, and whoconfuse the issue further by suspecting spider bites. Arterialpulses may be obscured by swelling. Time may be spent lookingfor fractures. The general medical condition is usually

. unfavourable, with obesity, uraemia, heart failure, diabetes,arteriosclerosis and various immediate disrurbances in themental state, the fluid balance, shock, etc. The angulated andreticular form of the skin necroses misleads one into diagnosing aprimary disorder of the arteries of the skin.

The collection of photographs which forms our main personalcontribution in this article is designed to direct anention to somefearures of the condition and its management. The firstrequirement after considering the diagnostic possibility ofnecrotizing fasciitis is bacteriological study. This shouldcomprise direct Gram-staining of smears from the exudate,syringe puncrure and aspiration of a swollen area near to (bur notat) a site of ulceration for aerobic and anaerobic culture, and abiood culrure. The choice of antibiotics can be decided on the

smear, failing which a combination of penicillin and cloxacillinplus coverage for Gram-negative organisms can be given. Itshould be borne in mind that the healing stages can becomplicated by subsequent infections in the raw area which maycall for a modification of the treatment.

As can be seen from our series, none of the patients was treatedby the primary surgery which Meleney2 thought was vital. It isquite possible that a plaque of necrotizing fasciitis obstructs theflow ofblood and lymph from the dermis mechanically, and earlyincision would relieve the tension, limit the spread of gangrene,and make the final repair more manageable. Thus, by shorteningthe illness some of the cumulative morbidity may be averted.

HypercoagulabilityThe development of acure cholecystitis in the case illustrated

by Fig. 13 is of special interest. Acalculous cholecystitis is aserious, often fatal disease that is seen among patients sufferingfrom bacterial sepsis, burns, trauma and cancer. II These clinicalconditions may be associated with the activation of factor XII(Hageman factor) and consequently the intrinsic pathway ofblood coagulation. In order to test this hypothesis, Becker et al. 12

injected E. coli endotoxin intravenously into dogs. This resultedin thrombosis of vessels and necrosis that was most marked in theserosa and muscularis of the gallbladder. These authors suggestthat the bloodvessels of the gallbladder are specially sensitive tothe activation in vivo of factor XII. The aggressivehypercoagulability found in the cases of necrotizing fasciitis(illustrated by Figs 11, 12 and 13) may provide additionalsupport for this view. It could also support the concept ofgallbladder necrosis as part of a Shwarrzman-Sanarelliphenomenon, as proposed by Vorster er al. 13,14

Summary

Advances in breast reconstruction make it a f~asible

and worthwhile operation. Three cases arepresented, illustrating two methods of breastreconstruction and the results achieved. Themethod used is determined by the type of trea~mentoriginally carried out. Several problems which maybe encountered are discussed.

S Alr.Med J 1982; 62: 131-134.

The restoration of the female body after ablative surgery forcarcinoma of the breast has been performed, often with poorresults, for many years. The advances in breast reconstructionover the last 5 years have been dramatic and rewarding for boththe patient and the surgeon.

Two basic methods of breast reconstruction are used. Firstly,in cases where extra skin and muscle cover is required, forinstance after radical mastectomy or radiation therapy, alatissimus dorsi myocutaneous flap is used. This provides bulk torestore the deformity due to the removal of the pectoralis majormuscle, as well as ensuring adequate cover for the silicone breastprosthesis. The second method merely involves the insertion ofthe silicone prosthesis into a pocket created beneath thepectoralis major muscle. This method is used following a simplemastectomy or a modified"radical mastectomy.

During the last 2 years we have performed 22 suchreconstructions; 8 of these involved the use of a latissimus dorsi

myocuraneous flap and in the remainder subpectoral insertion ofthe silicone prosthesis was undertaken. In most cases anoperative adjustment on the normal breast was necessary toanain symmetry. This involved either breast reduction, breastlift, or breast augmentation using a silicone prosthesis.

Three cases are presented, showing the two basic methods ofbreast reconstruction. Some of the problems that can beencountered are outlined.

Case reports

Case 1A 48-year-old woman presented 12 years after radical

mastectomy and postoperative radiotherapy to the axilla andchest wall for carcinoma of the breast (Fig. 1). Extra skin andmuscle cover was needed for the breast reconstruction.

Bostwick el al. 'Si method of breast reconstruction was used;this entails elevation and anterior transposition of a latissimusdorsi myocutaneous flap. A skin island, the size of which isdetermined by the estimated skin deficit, is designed over thelatissimus dorsi muscle. The skin island can be vertically,obliquely or transversely positioned on the muscle, dependingon the mastectomy scar. The skin island required is incised downto the muscle and secured to it by 3/0 silk sutures to prevent itfrom becoming detached from the muscle. The entire latissimusdorsi muscle is identified and elevated from the chest wall,working from the lowest point upwards.
