Experiencia y manejo de dos casos de gangrena de Fournier en pacientes pediátricos en el Instituto Nacional de Salud del Niño - San Borja / Experience and management of two cases of fournier's gangrene in pediatric patients at the Instituto Nacional de Salud del Niño - San Borja, Lima, Peru

RESUMEN La gangrena de Fournier es una patología que se encuentra predominantemente en varones adultos y extremadamente rara en niños. Se han descrito múltiples factores predisponentes en los niños, incluyendo la circuncisión, la dermatitis del pañal, la presencia de abscesos, traumatismos anorrectales y deficiencias inmunológicas. Los signos y síntomas característicos incluyen edema e hiperemia de rápida evolución en la región perineal acompañados de dolor intenso y fiebre. Una vez que se diagnostica la gangrena de Fournier, se debe instaurar tratamiento de forma inmediata, antibióticos endovenosos de amplio espectro y debridamiento quirúrgico temprano del tejido desvitalizado. A continuación presentamos un reporte de casos que incluye las características clínicas y epidemiológicas de dos pacientes pediátricos con gangrena de Fournier que recibieron tratamiento médico y quirúrgico en el Instituto Nacional de Salud del Niño de San Borja.

ABSTRACT Fournier's gangrene is a condition mainly found in adults and it very rarely occurs in children. Multiple predisposing factors have been identified for children, including circumcision, diaper dermatitis, the occurrence of abscesses, anorectal trauma, and immune deficiency. Characteristic signs and symptoms include rapidly progressing edema and hyperemia in the perineal region, accompanied by intense pain and fever. Once Fournier's gangrene is diagnosed, therapy must be immediately instituted, using wide spectrum intravenous antibiotics and early surgical debridement of devitalized tissues. We present a case report including clinical and epidemiological characteristics of two pediatric patients with Fournier's gangrene who received medical and surgical therapy at the Instituto Nacional de Salud del Niño in San Borja, Lima, Peru.

Role of erythrocyte sedimentation rate and C-reactive protein as a predictor of severity of cellulitis and necrotising fasciitis

Background: Skin infections are major cause of morbidity and mortality worldwide, affecting more than one person/1000 person/year. Sepsis has a worldwide incidence of more than 20 million cases a year, with mortality due to septic shock reaching up to 50% even in industrialized countries. Acute phase reactants like erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) have been used traditionally as markers for inflammation and are readily available in most centres. Aim was to study the correlation between the values of ESR and CRP with severity of cellulitis and necrotising fasciitis (in term of hospital stay and disease outcome).Methods: This was a prospective observational study conducted at Department of Surgery, GMC and Hamidia Hospital, Bhopal from a period of March 2016 to August 2018.Results: Skin and soft tissue infections are most commonly affects male, diabetes mellitus most common co-morbid condition. Mean value of ESR and CRP in patients who could not survived was 64.44 and 145.92 respectively and value more than 54.95 and 93.41 requires longer hospital stay.Conclusions: ESR and CRP are non-specific test but they are good predictors of severity of cellulitis and necrotising fasciitis not only in planning of management of these cases but also predicting outcome of the disease.

Extensive fournier gangrene with retroperitoneal involvement in a diabetic patient

Fournier’s gangrene is a rare, rapidly progressive, fulminant form of necrotizing fasciitis of the genital, perianal and perineal regions extending to the abdominal wall between the fascial planes. It is secondary to polymicrobial infection by aerobic and anaerobic bacteria with a synergistic action. A 42 year old male who is an alcoholic and diabetic on irregular treatment presented with scrotal swelling and pain for 5 days following a trauma. On examination, patient was febrile, tachypneic and had tachycardia. His scrotum was edematous and erythematous on right side with crepitus. Abdomen was warm on right side till umbilicus and had crepitus. He was in sepsis and had diabetic ketoacidosis, prerenal azotemia and mild impairment of liver function. A diagnosis of extensive Fournier gangrene with retroperitoneal involvement was made. Patient underwent scrotal exploration and aggressive debridement serially. Testis was spared. As patient improved with good wound care and glycemic control, wound was closed. Though our patient had retroperitoneal involvement without peritonitis, he was deferred laparotomy which significantly reduced the morbidity and mortality. It is one of the few reported case in the literature with retroperitoneal involvement.

Case report on necrotizing fasciitis following episiotomy

Necrotising fasciitis (NF) is an extremely rare but near fatal bacterial soft tissue infection, complicating the operative wounds. Here is a case report of Necrotising fasciitis in episiotomy wound in low socioeconomic, poorly nourished and anaemic women. A 39 years old, second gravida, delivered normally with medio-lateral episiotomy under local anaesthesia. On postnatal day four, patient developed high grade fever and on examination episiotomy was found to be unhealthy and gaped. She was started on broad spectrum antibiotics empirically but the cellulitis rapidly progressed to vulva, then to the bilateral thighs and extended till knees. Bilateral lower limb Doppler ultrasonography was done to rule out deep vein thrombosis which showed no abnormality. USG abdomen revealed huge pus collection in the lower abdomen. Under anaesthesia, surgical exploration was done, pus was drained followed by wound debridement and pus sent for culture and sensitivity. Pus and blood culture showed growth of Klebsiella pneumoniae, so started on appropriate antibiotics. Patient started recovering, when the wound was healthy, secondary suturing of episiotomy wound done. She was discharged on post-natal day 27 after full recovery. Early diagnosis and aggressive timely management are the corner stone to avoid morbidity and mortality of NF.

Early clinical manifestations of vibrio necrotising fasciitis

We present five patients with vibrio necrotising fasciitis, a lethal and disabling disease. Two of these patients had a history of exposure to either warm seawater or raw/live seafood, three had underlying chronic liver disease, and four presented with hypotension and fever. There were three deaths and four patients required intensive care unit stays. Among the two survivors, one had high morbidity. Only one patient met the criteria of Laboratory Risk Indicator for Necrotising Fasciitis score > 6. A clinician should suspect possible vibrio necrotising fasciitis if the following are present: contact with fresh seafood/warm seawater, a known history of chronic liver disease and pain that is out of proportion to cutaneous signs. All patients must be managed via intensive care in high dependency units. We recommend a two-step surgical protocol for patient management involving an initial local debridement, followed by a second-stage radical debridement and skin grafting.

Abdominal wall necrotising fasciitis: A rare but devastating complication of the percutaneous endoscopic gastrostomy procedure

Percutaneous Endoscopic Gastrostomy (PEG) tubes were often offered to patients requiring long term enteral feeding. Even though the procedure is relatively safe, it is associated with various complications such as peritonitis or even death. 1 We presented a case of a 54-year-old gentleman with underlying ischemic stroke and pus discharges from a recently inserted PEG tube. Computed Topography (CT) scan confirmed abdominal wall necrotising fasciitis complicated with hyperosmolar hyperglycaemia state (HHS) and later succumbed after 48 hours of admission. Our case illustrated the rare complication related to the insertion of PEG tube; abdominal wall necrotising fasciitis that was associated with mortality.

Determining if Positive Predictive Value using Laboratory Risk Indicator for Necrotising Fasciitis is Applicable in Malaysian Patients with Necrotising Fasciitis

Introduction: Necrotising fasciitis (NF) is a rapidly progressive infection of the subcutaneous tissue and fascia which spreads rapidly. The scoring system of Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) developed by Wong et al has been proposed as a tool for distinguishing NF and other soft tissue infections (STI) in Singapore. We set out to establish whether the LRINEC score is applicable in our Malaysian setting. Materials and Methods: A cross sectional study of all patients admitted to our hospital diagnosed with NF or To Rule Out NF (TRO NF) between January 1st 2016 to 30th June 2016. The sensitivity, specificity, positive and negative predictive values were then calculated for LRINEC score of ≥ 6 and ≥ 8. Results: Fourty-four patients were identified with the diagnosis of NF or TRO NF in the study. Twenty-seven patients (61.4%) were deemed post-operatively as having NF and 17 patients (38.6%) not having NF. A sensitivity of 59.3% and specificity of 47.1% when a LRINEC score of ≥ 6 was taken with positive predictive value (PPV) of 64.0% and the negative predictive value (NPV) of 42.1%. When score ≥ 8 was taken, the sensitivity was 48.1% and specificity of 58.8% with PPV of 65% and NPV of 41.7%. Conclusion: The low sensitivity and low PPV achieved in this study as well as other studies makes the LRINEC score unsuitable to be used solely to distinguish NF with other soft tissue infections.

Fournier’s Gangrene- Presentation and Outcome.

Background: Fournier’s gangrene (FG) is an acute, rapidly progressive, and potentially fatal, infective necrotizing fasciitis affecting the external genitalia, perineal or perianal regions, which commonly affects men, but can also occur in women and children factors associated with the mortality rate among patients admitted with clinical diagnosis of FG have been described in this study. Materials and Methods: This study was conducted in the Department of Surgery, JSS Medical College and Hospital from September 2014 to September 2016 on 30 patients admitted with a clinical diagnosis of FG over a period of 2-year. Data on demographics, clinical history and physical examination, vital signs, and laboratory values on admission were recorded on a designed data collection sheet. The patients were stratified according to factors associated with mortality using Chi-squared and independent t-test. Results: The disease-related hospital mortality rate was 13.3% (4/30). The median hospital stay was 15 days. The median age of the 30 patients was 45 years. The patients that did not survive were significantly older than those that survived (48.5 ± 15.15 vs. 45.3 ± 13.17 years) (P = 0.7). Diabetes mellitus (DM) was the most common risk factor accounting for 93.3% of the cases. Ischemic heart disease (IHD) at presentation was significantly associated with mortality with a rate of 50% among patients. The urogenital tract source of infection was associated with increased mortality (P = 0.4). Escherichia coli and Staphylococcus aureus were the most common pathogens isolated. The number of debridement did not differ significantly between survivors and nonsurvivors. Abdominal involvement was also significantly associated with higher mortality. There was no factor that was independently associated with mortality after multiple logistic regression analysis. Conclusion: FG remains a potentially fatal condition in our environment with a mortality rate of 13.3%. On univariate analysis, an older age, presence of IHD on admission, a urogenital source of infection, severe sepsis, and abdominal involvement are associated with mortality in our environment. The presence of DM, delay in presentation, and number of surgical debridement does not seem to affect mortality in our environment.

A rare glimpse into the morbid world of necrotising fasciitis: Flesh‑eating bacteria Vibrio vulnificus.

Necrotising fasciitis is one of the fatal skin and soft tissue infections. Vibrio vulnificus is a rare cause of necrotising fasciitis; however, the disease is one of the major manifestations of the bacteria. Here, we report one such case in a middle‑aged male patient. He presented with the signs of bilateral lower limb cellulitis and altered sensorium. V. vulnificus was isolated from blood culture and also from debrided tissue. Though the organism is well characterised, it is a rare causative agent of necrotising fasciitis. This case is a re‑emphasis on active look out for this bacterium in patients presenting with necrotizsing fasciitis.

Benign Subcutaneous Emphysema of the Upper Limb: A Case Report

Subcutaneous emphysema is the presence of gas or air in the subcutaneous tissue plane. The term is generally used to describe any soft tissue emphysema of the body wall or limbs, it can result from benign causes, most commonly secondary to trauma or from a life-threatening infection by gas gangrene or necrotising fasciitis. A case of subcutaneous emphysema involving the upper limb resulting from a trivial laceration to the elbow is reported and the importance of distinguishing between the two causes of subcutaneous emphysema is highlighted.

Fatal Necrotising Soft Tissue Infection Following Human Bite; a Case Report and Review of Literature.

Human bite injuries are one of the commonest bite injuries seen in the emergency room in a developing country. This bite injury can occasionally lead to devastating complications but yet, one of the most neglected injuries by both the victims and inexperienced attending Clinician. We present a case of fatal and extensive necrotising fasciitis by Eschcerecia coli following human bite by a schizophrenic patient.

Necrotising fasciitis of the Lower limb caused by Community-Acquired Methicillin-Resistant Staphylococcus aureus

Necrotising fasciitis caused by Community-Acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA) has emerged as a new entity. Although it is recognised worldwide, there have been no reported cases to date in Malaysia. We report a case of necrotising fasciitis of the left lower limb in an otherwise healthy 20-year-old man. He presented with septic shock and despite the paucity of clinical signs in the limb, the infection was aggressive. Methicillin-Resistant Staphylococcus aureus (MRSA) was isolated from the deep fascia of the leg. Panton-Valentine leucocidin gene (PVL), which is a stable genetic marker for CA-MRSA strain, was positive in this case. This case of community acquired MRSA necrotising fasciitis is of concern and may herald the emergence of this resistant organism in Malaysia. Vigilant surveillance and microbiological monitoring is needed to follow this CA-MRSA trend.
