Severe hypotony and filtering bleb leak after intravitreal injection of ranibizumab

We report a case of a patient with age-related macular degeneration, who had undergone trabeculectomy nine years earlier, and developed severe hypotony and bleb leak after treatment with intravitreal injections of ranibizumab. Although the incident is rare, in patients with longstanding filtering blebs, who need treatment with antivascular endothelial growth factors, close follow-up may be advocated, since the occurrence of bleb rupture could lead to permanent vision loss

Nd: YAG capsulotomy for posterior capsule opacification after combined clear corneal phacoemulsification and vitrectomy

Ilias Georgalas1, Petros Petrou2, George Kalantzis2, Dimitrios Papaconstantinou2, Chrysanthi Koutsandrea2, Ioannis Ladas21Department of Ophthalmology, “G. Gennimatas” Hospital of Athens, NHS, Athens, Greece; 2Department of Ophthalmology, University of Athens, Athens, GreecePurpose: To evaluate the efficacy and safety of Neodymium:YAG (Nd:YAG) laser capsulotomy for posterior capsule opacification (PCO) following combined phacoemulsification and vitrectomy for the treatment of cataract in association with macular hole (MH) or epiretinal membrane (ERM).Methods: Retrospective clinical study of 34 eyes of 34 patients who underwent combined cataract surgery and vitrectomy, developed PCO, and subsequently underwent Nd:YAG laser capsulotomy. Follow-up examinations included visual acuity measurement, evaluation of intraocular lens (IOL) centration, intraocular pressure (IOP) measurement, and dilated fundus examination.Results: Nd:YAG laser capsulotomy was performed in all 34 eyes. The mean age of the patients was 65.08 years (range 45–87) and the mean follow up period was 11.05 months (range 4–23). The mean time elapsed between the last intraocular operation and the development of PCO was 10.00 months for patients with previous ERM and 15.33 for those with MH (P = 0.001, t-test for equality of means). None of our patients developed recurrence of MH, retinal detachment, IOL dislocation, or permanent IOP elevation.Conclusion: In our study, the most remarkable observation is that no complication occurred after the YAG capsulotomy, possibly because the eyes were vitrectomized and vitreous seems to play an important role in the occurrence of post-Nd:YAG complications. In addition we noted that PCO seems to occur earlier in the eyes undergoing combined surgery for cataract and ERM when compared with those where combined phacoemulsification and vitrectomy are performed for cataract and MH.Keywords: Nd:YAG capsulotomy, phacoemulsification, vitrectom

Successful Treatment of a Severe Case of Fournier's Gangrene Complicating a Perianal Abscess

A 67-year-old male patient with diabetes mellitus and nephritic syndrome under cortisone treatment was admitted to our hospital with fever and severe perianal pain. Upon physical examination, a perianal abscess was identified. Furthermore, the scrotum was gangrenous with extensive cellulitis of the perineum and left lower abdominal wall. Crepitations between the skin and fascia were palpable. A diagnosis of Fournier's gangrene was made. He was treated with immediate extensive surgical debridement under general anesthesia. The patient received broad-spectrum antibiotics, and repeated extensive debridements were performed until healthy granulation was present in the wound. Due to the fact that his left testicle was severely exposed, it was transpositioned into a subcutaneous pocket in the inner side of the left thigh. He was finally discharged on the 57th postoperative day. Fournier's gangrene is characterized by high mortality rates, ranging from 15% to 50% and is an acute surgical emergency. The mainstay of treatment should be open drainage and early aggressive surgical debridement of all necrotic tissue, followed by broad-spectrum antibiotics therapy

The use of axially vascularised flaps in reconstructing dehiscent surgical wounds

Purpose: The purpose of the study is to present the indications and evaluate the effectiveness of axial regional flaps in treating dehiscent surgical traumas.Materials - Methods: During the last three years, 11 patients (7 male, 4 female) underwent a reconstructive operation for a dehiscent surgical wound, which resulted after an orthopaedic, vascular, cardiovascular or urological surgery. Trauma de­hiscence was related to ischemia due to prior radiotherapy, haematoma formation, infection or previous scarring. Prosthetic implants were exposed in five cases. All patients had one to three attempts for primary closure before they were seen by the plastic surgeon. In all cases, a pedicle axial flap was used: a muscle or musculocutaneous flap for managing traumas located over the torso (n = 7), and fasciocutaneous (n = 3) or muscle (n = 1) flaps for those located on the extremities.Results: Follow-up ranged from 2 to 7 months. In all cases, flaps provided safe closure and sufficient coverage of the wound; exposed implants were not removed. No recurrences were recorded. We had a partial necrosis of the skin island in a musculocutaneous pectoralis major flap used for covering a sternal defect; revision consisted in debridement and secondary coverage with a skin graft.Conclusion: Axial flaps offer reliable solutions when we face dehiscent surgical traumas. The appropriate flap is chosen according to the location, size and other characteristics of the defect. Muscle flaps are mostly indicated for reconstructing complicated wounds over the torso, especially in previously irradiated areas, while fasciocutaneous flaps are used for com­plicated traumas of the extremities

Coexistence of gastrointestinal stromal tumor (GIST) and colorectal adenocarcinoma: A case report

<p>Abstract</p> <p>Background</p> <p>Gastrointestinal stromal tumors (GIST) represent the most common mesenchymal tumors of the digestive tract. Over the last ten years the management of GISTs has dramatically altered but their coexistence with other gasrointesinal tumors of different histogenesis presents a special interest. The coexistence of GISTs with other primaries is usually discovered incidentally during GI surgery for carcinomas.</p> <p>Case presentation</p> <p>We present here, a case of a 66-year-old patient with intestinal GIST and a synchronous colorectal adenocarcinoma discovered incidentally during surgical treatment of the recurrent GIST. Immunohistochemical examination revealed the concurrence of histologically proved GIST (strongly positive staining for c-kit, vimentin, SMA, and focal positive in S-100, while CD-34 was negative) and Dukes Stage C, (T3, N3, M0 according the TNM staging classification of colorectal cancer).</p> <p>Conclusion</p> <p>The coexistence of GIST with either synchronous or metachronous colorectal cancer represents a phenomenon with increasing number of relative reports in the literature the last 5 years. In any case of GIST the surgeon should be alert to recognize a possible coexistent tumor with different histological origin and to perform a thorough preoperative and intraoperative control. The correct diagnosis before and at the time of the surgical procedure is the cornerstone that secures the patients' best prognosis.</p

Synchronous gastric adenocarcinoma and gastrointestinal stromal tumor (GIST) of the stomach: A case report

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms of the gastrointestinal tract (1%), and stomach is the most common location involved. However, the co-existence of gastric adenocarcinoma and GIST is very rare. A case of an 80-year-old male with a simultaneous presentation of a gastric adenocarcinoma and GIST is presented. Various hypotheses have been proposed in order to explain this rare simultaneous development, but even though it's cause has not been proven yet

Peripheral capillary non-perfusion in asymptomatic Waldenström's macroglobulinemia

<p>Abstract</p> <p>Background</p> <p>To report the rare association of peripheral retinal ischemia in a patient with Waldenström's macroglobulinemia.</p> <p>Case Presentation</p> <p>A 39-year old man with a recent diagnosis of asymptomatic Waldenström's macroglobulinemia (WM) was referred from his physician for ocular evaluation. The fundus examination in his right eye (RE) revealed very mild central vein dilation, while retinal hemorrhages associated with microaneurismal alterations of the vascular plexus were detected at the temporal periphery. Fluoroscein angiography of his RE revealed an extended area of capillary dropout distal to the microaneurismal lesions. In our patient with WM an extensive area of capillary non-perfusion, in the absence of severe involvement of the posterior pole was documented; this association to the best of our knowledge has never been reported before.</p> <p>Conclusion</p> <p>Although the incidence of the disease is rare, meticulous examination of the retinal periphery should be performed in all patients with WM and vice versa the differential diagnosis of peripheral retinal ischemia of unknown origin should include an investigation to rule out asymptomatic Waldenström's macroglobulinemia.</p

Inflammatory pseudotumor associated with Mycobacterium tuberculosis infection

SummaryBackgroundInflammatory pseudotumor is a relatively rare entity; originally identified in the lung, it has been described in multiple extrapulmonary anatomic locations.Case reportWe report on the unusual case of an inflammatory pseudotumor associated with Mycobacterium tuberculosis infection, which was initially mistaken for a renal malignancy both in clinical and radiological settings. We additionally present three brief reviews concerning: (1) infectious agents postulated to induce morphological changes of an inflammatory pseudotumor; (2) mycobacterial pseudotumors; and (3) distinction from inflammatory myofibroblastic tumors of the renal pelvis.ConclusionsThe present case highlights the diagnostic importance of PCR-based detection of mycobacterial DNA in granulomatous tissue responses. It is of crucial importance that clinicians are aware of this unusual manifestation of mycobacterial infection to ensure that pertinent laboratory evaluation is employed and appropriate treatment is administered in order to avoid potential clinical implications
