Vacuum-assisted closure treatment of leg skin necrosis after angiographic embolization of a giant plexiform neurofibroma

Type 1 neurofibromatosis is a relatively common inherited disease of the nervous system, with a frequency of almost 1 in 3000. It is associated with neurofibromas of various sites. Our case report is about the surgical management of a giant neurofibroma of the right gluteal fold in a 46-year-old male with NF1. The patient presented with increasing edema and accelerated growth of the mass; he underwent percutaneous embolization of lesion vessels that induced necrosis of the neurofibroma. The patient was taken to the operating room, where surgical resection of the bulk of the lesion was undertaken. The postoperative course was complicated by delayed wound closure managed with antibiotics and vacuum-assisted wound closure. Giant neurofibromas similar to this tumor require complex preoperative, intraoperative and postoperative management strategies. Surgical debulk is best managed with preoperative percutaneous embolization that help to avoid surgical bleeding. Postoperative delayed wound closure was managed with the application of negative pressure in a closed environment that triggers granulation and tissue formation.

Risk factors in reoperative thyroid surgery for recurrent goitre. Our experience

Aim. Reoperative thyroid surgery is an uncommon operation associated with a higher complication rate; we reviewed our series of patients on whom reoperative thyroid surgery was performed.Method. 106 patients had a thyroid reoperation for recurrent multinodular goiter (93 patients), recurrent thyrotoxicosis (3) or suspected malignancy (10); bilateral completion thyroidectomy was performed in 68 cases, lobectomy in 36, removal of a mediastinal recurrence and of a pyramidal remnant in 1 patient respectively. Results. Temporary hypoparathyroidism occurred in 41 patients (38.67%), definitive in 7 (6.6%), transient recurrent laryngeal nerve palsy in 5 (4.71%), permanent nerve palsy in 1 (0.94%); in 3 cases (2.83%) surgical revision of haemostasis was necessary for postoperative haemorrhage. After monolateral surgery we had 13 cases of transient hypoparathyroidism (34.21%), 2 of definitive (5.26%) and 1 transient recurrent laryngeal nerve palsy (2.63%); after bilateral surgery we had 29 cases of transient hypoparathyroidism (42.64%), 5 of definitive (7.35%), 4 of transient recurrent laryngeal nerve palsy (5.88%), 1 of definitive (1.47%) and 3 of postoperative bleeding (4.41%). Conclusions. Reoperative thyroid surgery is a technical challenge with a high incidence of complications. Scarring, edema and friability of the tissues together with distortion of the landmarks make reoperative surgery azardous. A higher risk of complications is described when previous surgery has been performed on both sides. Total thyroidectomy should be considered the procedure of choice for benign multinodular goiter eliminating the potential of a reoperation. Whenever necessary, reoperative hyroidectomy may be performed safely with little morbidity in experienced hands.

Whipple’s disease infection surgical treatment: presentation of a rare case and literature review

The Whipple’ Disease (W.D.) is a very rare disease with an incidence of 1 per 1.000.000 inhabitants; it is a systemic infection that may mimic a wide spectrum of clinical disorders, which may have a fatal outcome and affects mainly male 40-50 years old. The infective agent is an actinomycete, Tropheryma Whipplei (T.W.) that was isolated 100 years after first description by Wipple, and identified in macrophages of mucosa of the small intestine by biopsy which is characterized by periodic acid-Schiff-positive, products of the inner membrane of his polysaccharide bacterial cell wall. The multisystemic clinical manifestations evolve rapidly towards an organic decay characterized by weight loss, malabsorption, diarrhea, polyathralgia, opthalmoplegia, neuro-psychiatric disorders and sometimes associated to endocarditis. Early antibiotic treatment with trimethoprim and sulfometathaxazole reduces the fatal evolution of the disease. The authors present a rare experience about a female subject in which the clinical gastrointestinal signs were preceded by neuro-psychiatric disorders, and evolved into obstruction and intestinal perforation which required an emergency surgery with temporary ileostomy, recanalized only after adequate medical treatment with a full dose of antibiotic and resolution of clinical disease for the high risks of fistulae for the edema and lymphadenopathy of mucosa. The diagnosis was histologically examined by intestinal biopsy performed during surgery, which showed PAS-positive histiocytes, while PRC polymerase RNA was negative, which confirms the high sensibility of PAS positive and low specificity of RNA polymerase for T.W.

Gastric and Peritoneal Involvement of Human Herpes Virus 8 Related Kaposi Sarcoma in a Patient with Acquired Immunodeficiency Syndrome

Kaposi's sarcoma (KS) is one of the most frequent neoplastic diseases in patients infected with human immunodeficiency virus (HIV). The authors report the case of a 40-year-old male with ascites, peripheral edema and peritoneal carcinomatosis secondary to a gastric KS related to human herpes virus type 8 (HHV-8). The patient had severe immunodeficiency, with a TCD4+ count of 86 cells/µl and newly diagnosed acquired immunodeficiency syndrome. His clinical condition rapidly deteriorated, with multiorgan failure, and he died without the possibility of initiating antiretroviral therapy or chemotherapy. To the authors’ knowledge, carcinomatosis is a rare feature in KS.

A Very Big Hand Is a Very Big Problem: Soft-Tissue Infection, Venous Thrombosis, or Just an Insect Sting?

A 67-year-old woman developed severe edema of her right hand and forearm, for which she was treated with antibiotics, without benefit. The echography excluded a venous thrombosis. Subsequently, she referred a wasp sting before the development of the edema. Specific Hymenoptera venom immunoglobulin E (IgE) was found to be positive for paper wasp and yellow jacket. A large local reaction (LLR) was diagnosed due to the hymenoptera sting. Self-injectable epinephrine was prescribed for possible, though unlikely, systemic reactions following hymenoptera stings.
