ABSTRACT
Nicolau syndrome is a rare complication of the parenteral application of various drugs. It is characterized by the appearance of pain, followed by edema, erythema, and then a necrotic plaque. We present the case of a 31-year-old male with this syndrome, after the application of intramuscular benzathine penicillin. The diagnosis was supported by the biopsy. He received treatment with enoxaparin and cilostazol with subsequent improvement.

Se caracteriza por la aparición de dolor, seguido de edema, eritema y luego una placa necrótica. Se reporta el caso de un hombre de 31 años que presenta este síndrome luego de la aplicación de penicilina benzatínica intramuscular. La biopsia apoyó el diagnóstico.

Calcium hydroxide has been used successfully in root canal therapy for many years. However, it can cause serious damage if it is inadvertently displaced into surrounding vital structures, resulting in thrombosis if displaced into blood vessels, damaging connective tissue, and causing skin necrosis. These adverse reactions are known as Nicolau syndrome (NS) or embolia cutis medicamentosa. Very few case reports have been published about these adverse effects of injecting calcium hydroxide beyond the apex during root canal therapy. A 16-year-old female patient was referred to the endodontic department of Hamad Dental Center for assessment after treatment by the maxillofacial surgery department for swelling and tissue necrosis that occurred after endodontic treatment in another clinic. When the patient initially attended the maxillofacial surgery department, she presented with swelling on the left side in the region of the maxillary left first permanent molar. On examination, there was a change in the color of the skin of the left cheek in that area along with some reported paralysis of the left side of her lips. Analgesics and antibiotics had already been prescribed at the referring clinic. Two weeks later, the patient developed a necrotic patch of skin on the same area. Subsequent evaluation at the endodontic department of Hamad Dental Center led to a diagnosis of NS. NS is a very rare iatrogenic condition. Displacing calcium hydroxide beyond the apex might increase the chance of NS. Clinicians should avoid overinstrumentation and forced injection of calcium hydroxide to prevent NS.

The current COVID-19 pandemic is caused by the SARS-CoV-2 coronavirus. The initial recognized symptoms were respiratory, sometimes culminating in severe respiratory distress requiring ventilation, and causing death in a percentage of those infected. As time has passed, other symptoms have been recognized. The initial reports of cutaneous manifestations were from Italian dermatologists, probably because Italy was the first European country to be heavily affected by the pandemic. The overall clinical presentation, course and outcome of SARS-CoV-2 infection in children differ from those in adults as do the cutaneous manifestations of childhood. In this review, we summarize the current knowledge on the cutaneous manifestations of COVID-19 in children after thorough and critical review of articles published in the literature and from the personal experience of a large panel of paediatric dermatologists in Europe. In Part 1, we discuss one of the first and most widespread cutaneous manifestations of COVID-19, chilblain-like lesions, and in Part 2 we expanded to other manifestations, including erythema multiforme, urticaria and Kawasaki disease-like inflammatory multisystemic syndrome. In this part of the review, we discuss the histological findings of COVID-19 manifestations, and the testing and management of infected children for both COVID-19 and any other pre-existing conditions.

AIM: Intramuscular or, more rarely, local drug injection is occasionally followed by immediate local pain, livedoid skin lesions and, some days later, the development of ischemic lesions. This very uncommon but potentially severe reaction, termed Nicolau syndrome, is traditionally associated with bismuth and ß-lactam antimicrobials. The aim of this report was to review the literature associating Nicolau syndrome with the administration of non-steroidal anti-inflammatory drugs. METHODS: The National Library, Excerpta Medica, Web of Science and Cochrane library databases were used. RESULTS: Sixty-two cases (40 females and 22 males aged from 13 to 81, median 57 years) of Nicolau syndrome were published after 1992. Fifty-three cases occurred after diclofenac. The remaining nine cases were associated with ketoprofen (N = 2), ketorolac (N = 2), phenylbutazone (N = 2), etofenamate (N = 1), ibuprofen (N = 1) and piroxicam (N = 1). CONCLUSION: Although Nicolau syndrome is extremely uncommon, physicians must be aware of this complication after intramuscular administration of non-steroidal anti-inflammatory drugs and should avoid unnecessary injections.

BACKGROUND: Nicolau syndrome is a rare condition consisting in tissue ischemia and necrosis following intramuscular, intra-articular or subcutaneous injection. PATIENTS AND METHODS: Immediately after gluteal intramuscular injection of benzathine-penicillin, a 10-year-old male child presented an extensive painful violaceous lesion on the left buttock associated with urinary incontinence and left lower-limb paresis. Additional underlying muscular damage was supported by high serum levels of creatine kinase and lactate dehydrogenase. Treatment was based on fluid expansion, intravenous steroids and anticoagulants, resulting in improvement of cutaneous and muscular lesions. Improvement in terms of neurological dysfunction was obtained after regular neuromuscular rehabilitation. DISCUSSION: This case underlines the need to prevent Nicolau syndrome by means of compliance with the technical recommendations for intramuscular injections.

A 23 year-old man was admitted to the hospital with chief complaints of pain, edema and spasm of the left lower limb, as well as mottling of dorsal and plantar aspects of the foot. One week before the current admission, he was treated with oral co-amoxiclave and intramuscular penicillin 6.3.3. Immediately after the third injection, he experienced burning and yellowish discoloration at the site of the injection wich then progressed to his leg and foot. Pain, significant edema, spasm and mottling occurred within 30 minutes of the injection. The patient was referred to the hospital after 36 hours from the beginning of the symptoms. Color Doppler sonography revealed no impairment in the lower extremity flow and the common femoral artery, superficial femoral, popliteal, dorsalis pedis and posterior tibialis arteries were normal. Superficial probe sonography detected mild effusion in the left ankle without collection.

El síndrome de Nicolau (SN) es una complicación rara de la inyección de ciertos fármacos por vía intramuscular, intrarticular o subcutánea, que produce necrosis isquémica de la piel, las partes blandas y el tejido muscular circundante. La bencilpenicilina benzatínica es uno de los antibióticos más ampliamente empleados para las infecciones de las vías respiratorias altas y raramente se ha notificado que produzca SN. En este artículo presentamos el caso de un niño de sexo masculino de cuatro años de edad diagnosticado con SN tras la inyección de bencilpenicilina benzatínica tratado satisfactoriamente con heparina fraccionada (enoxaparina) y pentoxifilina. Los médicos deben estar atentos al uso innecesario de bencilpenicilina benzatínica para evitar las probables complicaciones.
Nicolau syndrome (NS) is a rare complication of intramuscular, intraarticular or subcutaneous injection of particular drugs leading to ischemic necrosis of the surrounding skin, soft tissue and muscular tissue. Benzathine penicilin one of the most widely used antibiotic for upper respiratory tract infections and has been rarely reported to cause NS. Here we describe a 4 year old boy with diagnosis of NS after the injection of benzathine penicillin who was successfuly treated with unfractionized heparin (enoxaparine) and pentoxifylline. The practitioners should pay attention for unnecessary use of benzathine penicillin to avoid from probable complications.
