Surgical treatment of acne inversa (hidradenitis suppurativa): a 20-year experience

EXPERIMENTAL DERMATOLOGY, Issue 6 2006
Wolfgang Hartschuh
Acne inversa (AI) is caused by follicular hyperkeratosis in intertriginous areas rich in apocrine glands followed by occlusion and rupture of the follicle and inflammation. Sinus tracts, scarring and often contraction with limitation in mobility may occur. There is a world-wide consensus that in chronic disease surgical removal of all involved tissue as early as possible is the most effective treatment modality. The aim of this study is to demonstrate our operative strategy, including postoperative wound care and prevention, the results and pitfalls in the treatment of AI. The operations are increasingly performed in tumescence anaesthesia, followed by secondary healing. Only removal of extended skin areas in the inguino-genital and ano-perineal regions demand general anaesthesia. In axillary regions, all hair-bearing skin including the sweat glands is removed to obtain a hair-free, dry skin area. In the other regions with ill-defined hair and apocrine gland areas, only involved indurated skin is excised. For early limited disease with fluctuant abscesses, unroofing instead of mere incision and drainage is a good first option. Professional wound care with shaving and stretching of the wound margins is very important to avoid premature wound closure. Locally applied disinfectant soaps and 2% triclosane ointments are effective in pre- and postoperative skin care. Follow-up evaluation and collaboration among surgeons and dermatologists and an improved insight in the pathogenesis of AI are mandatory for the successful long-term management of patients afflicted with this complex and debilitating disease.

Evaluation of radiographs, clinical signs and symptoms associated with pulp canal obliteration: an aid to treatment decision

DENTAL TRAUMATOLOGY, Issue 6 2009
Adeleke O. Oginni
The dental clinician faced with this condition has to make a difficult decision. The aim of this study was to evaluate the clinical signs and symptoms associated with teeth with PCO and to assess the status of the periapical tissues using the periapical index (PAI) as an aid in making a treatment decision. The study included teeth diagnosed with PCO in patients with a history of traumatic injury to the involved teeth. Histories of associated signs and symptoms including pain, swelling and drainage from a sinus tract were elicited. Tooth color, sensibility to electric pulp testing, mobility and percussion tenderness were recorded. The periapical status was assessed using the PAI. Two hundred and seventy-six teeth were diagnosed with PCO. One hundred and fifty-seven (56.9%) and 119 (43.1%) demonstrated partial or total PCO, respectively. Yellow discoloration presented most frequently, occurring in 186 (67.4%) teeth. Sixty-two (33.3%) of these had developed periapical lesions and reacted negatively to sensibility testing. Fifty-seven (30.7%) of these teeth presented radiographically with a normal periapical appearance and reacted normally to sensibility testing, whereas 67 (36.0%) presented with small changes in the periapical bone pattern and reacted in the high normal range to sensibility testing. Teeth with PAI scores ,2 presented with occasional spontaneous pain. Teeth with PAI scores ,3 presented with clinical symptoms and signs ranging from pain on percussion to spontaneous pain, and slight swelling to sinus tract drainage. Based on the findings of this study, endodontic treatment should be initiated in teeth with tenderness to percussion, PAI scores ,3 and a negative response to sensibility testing. [source]

Dental emergencies presenting to a dental teaching hospital due to complications from traumatic dental injuries

DENTAL TRAUMATOLOGY, Issue 4 2002
Suhad H. Al-JundiArticle first published online: 29 JUL 200
Abstract ,,,In Jordan, only two surveys of dental trauma have been carried out. The aim of this study was to determine the incidence and pattern of dental emergencies resulting from traumatic injuries, as well as treatment provided to children presenting with these dental emergencies. Over a 1-year period, 620 children presented to our pediatric dental clinics with dental emergencies; 195 (31%) of these emergencies were a consequence of dental trauma to 287 teeth and were included in the study. The average time between the trauma and the dental emergency was 5 months. Pain or sensitivity was the most frequent presenting symptom (31.3%) followed by swelling or sinus tract (17.4%). The age of these patients ranged from 15 months to 14 years, with an average age of 9.3 years. Males accounted for 75.4% of the children in the samples, whereas females accounted for only 24.6%. The main cause of dental trauma was falling during play (58.5%); the least common cause was motor vehicle accidents, accounting for only 1.5% of all injuries. Most of the dental injuries occurred at home (41.5%), around noon time. The most commonly involved teeth were permanent maxillary central incisors accounting for 79.5% of all teeth involved by dental trauma. The most frequently encountered type of trauma in this sample was crown fracture seen in 76.6% of the teeth . Soft tissue injuries were estimated to occur in 16.9% of the children. The treatment received by the children in the sample ranged from no active treatment (6.2%) to elaborate dental procedures such as pulp therapy (41.3%) and prosthetic replacement of missing teeth (5.1%).

Diagnosis and treatment of odontogenic cutaneous sinus tracts of endodontic origin: three case studies

INTERNATIONAL ENDODONTIC JOURNAL, Issue 3 2009
B. Pasternak-Júnior
Abstract Aim, To describe three cases of extraoral sinus tracts, related to infected teeth, which were initially misdiagnosed as skin lesions and inappropriately treated. Summary, The extraoral sinus tracts were initially misdiagnosed as skin lesions. Dermatological surgery was performed and antibiotics prescribed but the lesions did not resolve. Then, a dental cause was sought, and identified. Endodontic intervention resulted in resolution of the problem, confirming the initial misdiagnosis. Key learning points ,,Dermatologists and other medical practitioners should be aware that dental extraoral sinus tracts can be confused with skin lesions. ,,A dental aetiology, as part of a differential diagnosis, should be kept in mind with oro-facial skin lesions. ,,If an extraoral sinus tract is of endodontic origin, then elimination of infection through effective endodontic treatment will lead to resolution of the sinus tract. ,,Early correct diagnosis can prevent unnecessary and ineffective antibiotic therapy and/or surgical intervention.

Cytokeratin expression in squamous cell carcinoma arising from hidradenitis suppurativa (acne inversa)

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 9 2007
Ichiro Kurokawa
In both cases, type A (infundibular-like keratinized) epithelia were observed. In type A epithelia, CK 1 and 10 expressions were decreased, and CK 14 and 17 were detectable in the whole layers. CK 7, 8, 15, 16 and 18 were not detected in type A epithelia. In tumor nests of well-differentiated SCC, CK 1 and 10 expressions were downregulated, and CK 14 expression was upregulated. In tumor nests of poorly differentiated SCC, CK 1 and 10 were not expressed, but simple epithelial keratins (CK 8, 18 and 19) were expressed. These changes of CK expression are related to malignant transformation from the sinus tract (type A epithelium) in HS to SCC. [source]

Conservative treatment of patients with periapical lesions associated with extraoral sinus tracts

AUSTRALIAN ENDODONTIC JOURNAL, Issue 3 2007
Janir Alves Soares phd
Abstract This paper describes the clinical courses of three cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. All teeth involved had periradicular radiolucent areas noted on radiographic examination and extra-oral sinus tracts appearing on the chin with exudation and unpleasant aesthetic appearance. The adopted treatment protocol included treating the sinus tract surface simultaneously with the root canal therapy. After root canal shaping using 5.25% sodium hypochlorite solution, calcium hydroxide-based pastes associated with different vehicles were inserted into the root canal for 4 months, and were changed monthly. All the sinus tracts healed in 7 to 10 days. The apical lesions were completely repaired in a maximum period of 24 months. The treatment adopted provided a complete healing of the periapical lesions in a short follow-up period. Surgical repair of the cutaneous sinus tract was therefore unnecessary. [source]

Inguinal panniculitis in a young Tasmanian devil (Sarcophilus harrisii) caused by Mycobacterium mageritense

AUSTRALIAN VETERINARY JOURNAL, Issue 5 2010
G Reppas
A 1-year-old, entire male Tasmanian devil living in captivity was presented because of a nodular inguinal lesion that subsequently developed a draining sinus tract. A second, similar lesion developed later in the ipsilateral axillary region. A deep representative biopsy specimen of abnormal subcutaneous tissue showed chronic active pyogranulomatous inflammation and beaded Gram-positive and acid-fast bacilli situated in lipid vacuoles within the lesion. A rapidly growing Mycobacterium species, shown subsequently to be M. mageritense, was grown from a swab of the primary lesion. It was susceptible to tetracyclines (including doxycycline) and moxifloxacin in vitro. The lesions resolved following treatment with doxycycline monohydrate (50 mg PO once daily) and then moxifloxacin (10 mg/kg PO for 20 days). The infection probably resulted from inoculation of subcutaneous tissues by material containing this Mycobacterium following fight or bite injuries. The presentation is reminiscent of similar lesions attributable to rapidly growing mycobacterial infections of the subcutis observed in domestic cats and quolls. [source]

A congenital dermal sinus presenting the muscle fasciculation and hypertrophy

ACTA NEUROLOGICA SCANDINAVICA, Issue 5 2001
M. Takahashi
Objective, To report unique and unknown clinical features of muscle fasciculation and muscle hypertrophy in a case of congenital dermal sinus. Patients, A 16-year-old girl presented with continuous fasciculation, often cramp, and hypertrophy of the left calf muscle. The radiography showed spina bifida of L4, L5 and S1. MRI revealed dermal sinus tract from the skin dimple of the back to the dura mater, and connected to the intradural inclusion tumor. At surgery the inclusion tumor contained many short hairs, and the cauda equina were severely adherent. Microdissection of the tumor and the adhesion was performed. At 2 years after surgery fasciculation decreased but continued; however, painful cramps of the calf muscle do not occur. Conclusions, Short hairs of dermoid and the adherence might be irritative to the cauda equina. The hyperactivity of the stimulated motor neuron may cause the muscle fasciculation leading to hypertrophy of the calf muscle. [source]

Unusual CNS infection from a subtorcular dermal sinus

ACTA PAEDIATRICA, Issue 4 2010
PM Kanev
Abstract A 14-month-old toddler with a previously unrecognized dermal sinus tract presented with hydrocephalus and raised intracranial pressure. CT and MRI revealed a large posterior fossa dermoid mass. Cultures obtained from CSF and posterior fossa subdural empyema were positive for both Staphylococcus aureus and Escherichia coli. To the authors's knowledge, this is the first such report. Conclusion:, This case suggests that children who present with CNS infections with unusual pathogens should be carefully evaluated for the presence of anatomic abnormalities including dermal sinus tracts.

Equine dental disease Part 4: a long-term study of 400 cases: apical infections of cheek teeth

EQUINE VETERINARY JOURNAL, Issue 3 2000
P. M. Dixon
Summary Of 400 horses referred because of equine dental disease, 162 suffered from primary apical infections of their cheek teeth (CT), including 92 with maxillary CT infections and 70 with mandibular CT infections. Maxillary swellings and sinus tracts were more common (82 and 26% incidence, respectively) with infections of the rostral 3 maxillary CT, than with infections of the caudal 3 maxillary CT(39 and 5% incidence, respectively). Nasal discharge was more commonly present with caudal (95%) than rostral (23%) maxillary CT infections. Mandibular CT apical infections commonly had mandibular swellings (91%) and mandibular sinus tracts (59%) and these infections were closely related to eruption of the affected CT. A variety of treatments, including medical treatment, apical curettage, repulsion and oral extraction of affected teeth were utilised in these cases, with oral extraction appearing to be most satisfactory. Infections of caudal maxillary CT with a secondary paranasal sinusitis were most refractory to treatment, with a complete response to the initial treatment achieved in just 33% of these cases. Most other cases responded fully to their initial treatment. The long-term response to treatment was good in most cases. [source]

Cemental tear: a case report

INTERNATIONAL ENDODONTIC JOURNAL, Issue 1 2006
M. L. Stewart
Abstract Aim, To report a case of a cemental tear. Summary, A case is reported of a patient with a history of trauma, root canal treatment and retreatment procedures to eliminate recurring sinus tracts. An exploratory surgery, extraction, and biopsy resulted in a diagnosis of cemental tear. Key learning points, ,,The detachment of a fragment of cementum is described as a cemental tear. ,,Cemental tears have been reported in the periodontal literature associated with localized, rapid periodontal breakdown. Common causative factors are aging and traumatic occlusion but the exact aetiology is unknown. ,,Trauma may be considered as a potential aetiologic factor for cemental tears in addition to occlusal traumatism and aging.

Cutaneous heterotopic bronchogenic tissue in the scapular area

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2010
aduman Balaban Ad
ABSTRACT Cutaneous bronchogenic anomalies are very rare lesions, and most of them present as cysts and/or sinus tracts in the subcutaneous layer. We report a 15-year-old boy who presented with a crusted and papillomatous plaque over the right scapular region. Histopathological examination of this plaque revealed pseudostratified ciliated columnar epithelium with papillary invaginations that included mucinous material. The lesion had no cyst or sinus formation and was bordered with smooth muscle bundles in stroma. [source]

Endodontic re-treatment associated with the elimination of amalgam root-end filling through sinus tracts: A report of two cases

AUSTRALIAN ENDODONTIC JOURNAL, Issue 2 2009
Janir Alves Soares phd
Abstract Two patients presented with complaints of recurrent drainage of purulent exudate from sinus tracts, inflammation and pain after endodontic re-treatment of the maxillary left (Case 1) and right (Case 2) lateral incisors. The periapical lesions persisted after apical curettage, apicectomy and root-end filling with silver amalgam. Radiographic examination exposed the poor quality of the endodontic treatments and the silver amalgam root-end fillings, which were associated with periapical radiolucent areas in both teeth. The sinus tract persisted after root canal cleaning and shaping, followed by a calcium hydroxide root canal dressing. The root-end fillings were periapically dislodged with endodontic K-files, and showed progressive displacement by sinus tracts up to elimination in the oral cavity. Follow ups of 42 and 65 months post procedure revealed clinical disappearance of the symptoms, sinus tracts and exudates, and radiographs revealed that the repair process of the periapical radiolucent areas was quite advanced.
