Effective and enduring surgical treatment for targeted therapy-related paronychia: A retrospective study

The development of targeted therapy has improved treatment outcomes for patients with non-small cell lung cancer (NSCLC). However, paronychia, a common adverse effect of targeted therapy, remains burdensome. Although conservative treatments for paronychia have been well reported in the literature, studies on the efficacy of surgical partial matricectomy for paronychia, are scarce. This study aimed to evaluate the effect of surgical partial matricectomy in targeted therapy-induced paronychia in patients with NSCLC. This retrospective cohort study included 11 patients with a total of 18 lesions on the big toes. Data on lung cancer stages, types and duration of targeted therapy, onset of paronychia, pain scale scores, conservative treatments, course of matricectomy, paronychia-free interval after matricectomy, and wound condition were collected from medical records. The Wilcoxon signed-rank test was used for analysis. The mean pain scale score after matricectomy was significantly lower than that after conservative treatments (1.00 ± 0.00 vs 2.94 ± 0.87; P < .001) and before treatment (1.00 ± 0.00 vs 3.06 ± 0.80; P < .001). The mean duration of matricectomy was significantly shorter than that of conservative treatments (3.22 ± 1.00 vs 56.56 ± 52.29 weeks; P < .001). Surgical partial matricectomy is an effective and enduring intervention for targeted therapy-related paronychia. It provides a shorter course of treatment, reduced pain, and improved appearance of the healed wound. Furthermore, surgical partial matricectomy could result in a better quality of life during targeted therapy than that of conservative treatments.

Management of Paronychia in Patients With Apert Syndrome

Apert syndrome is a complex congenital syndrome that includes bicoronal craniosynostosis, craniofacial dysmorphologies, cleft palate, hearing loss, spina bifida occulta, cardiac anomalies, and affects the upper and lower extremities-producing complex syndactyly in these patients. Management of the hands yields several challenges and mandates close follow-up to balance repair of complex polysyndactyly with other pressing interventions, such as posterior cranial vault distraction and surgical management of the airway. Our goals of therapy for the hands are to preserve 10 digits, provide sufficient soft tissue coverage, optimize hand function, and minimize the number of surgical interventions. Ideally, surgical management of the hand differences occurs between the ages of 9 months and 2 years, to optimize neurocognitive development. In complex syndactyly observed in patients with Apert syndrome, there are broad, conjoined nail plates that overlie the fused digits, and paronychia occurs frequently. Suppurative infections can delay definitive surgical intervention for the patient's complex syndactyly, and resolution of paronychia is critical. This study aims to propose an effective and safe technique to manage paronychia when it occurs in patients with Apert complex syndactyly and to mitigate the length of delay to definitive polysyndactyly reconstruction. In the context of these patients' need for multiple surgical interventions within the first few years of life, this strategy for preventing or mitigating paronychia can play an important role in streamlining their complex surgical management while avoiding multiple cancellations.

Toe keloid after nail extraction treated with surgical excision: A case report

RATIONALE

In this study, a case of toe keloid after nail extraction is presented, in which the keloids on both toes were resected by surgical excision. Keloids (from the Greek word meaning "crab's claw") are fibrous growths that extend beyond the original area of injury to involve the adjacent normal skin. In general, keloid tendencies appear to be regionally isolated to keloid-prone areas, such as the chest, ears, and deltoid regions, whereas the hands and feet are usually spared, which is why this case is meaningful.

PATIENT CONCERNS

A 20-year-old Chinese man had paronychia on both halluxes when he was 16 years old. He underwent a nail extraction at the age of 17. The nails of both halluxes were removed by nail extraction. This operation was successful, and the postoperative course was uneventful. After 6 months, the scars of the nail extraction on both sides began to exhibit hyperplasia and became red and swollen with itching. Later, the scar expanded and eroded the tissue beyond the matrix unguis. The whole matrix unguis was destroyed, and the nails were distorted. The scars began to ulcerate after 2 years. The patient used potassium permanganate to clean his wounds, but the keloid scars did not improve.

DIAGNOSES

The patient was diagnosed as toe keloid based on his history and symptoms. The biopsy result supported our diagnoses.

INTERVENTIONS

The toe keloids were effectively cured by surgical excision and skin flap transplantation combined with postoperative irradiation and hyperbaric oxygen (HBO) treatment.

OUTCOMES

No recurrence was detected during the period from 6 to 24 months of follow-up after the surgery.

LESSONS

In this case, the trauma of the nail extraction was likely the key cause of the keloid. However, the patient was also predisposed to keloids, as we observed keloids on his chest. In general, keloid tendencies appear to be regionally isolated to keloid-prone areas such as the chest, ears, and deltoid regions, whereas the hands and feet are usually spared, which is why this case is meaningful.

[Surgical treatment of ingrown toenail and paronychia with lateral toe incision]

OBJECTIVE

To investigate and compare the advantages of surgical treatment of ingrown toenail with the traditional Winograd method.

METHODS

From Aug.2013 to Jun.2015,77 cases (89 toes) with 15-58 years were involved in the study.37 cases (42 toes) were treated with Winograd method and other 40 cases (47 toes) were treated with a method using lateral incision without cutting the nail fold. The time of returning to normal activities, infection rate, recurrence rate, pain VAS score and shape satisfaction VAS score were evaluated to display the aesthetic and functional result of the both methods.

RESULTS

All patients were followed up with an average of 8.6 months. The patients treated with the novel method returned to normal activities after (5.3 ± 0.5) d post-surgery, which was much shorter than that (7.3 ± 0.6) d in patients with the Winograd method (P ＜ 0.05).And the infection rate in the lateral incision group was also lower than that in the Winograd method group (P ＜ 0.05).At 3 days post-surgery, the pain VAS score in Winograd method group was higher (P ＜ 0.05),but the difference of pain VAS score disappeared after 1 and 6 months post-surgery (P ＞ 0.05).The shape satisfaction VAS score were 9.2 ± 0.6 in the lateral incision group and 7.1 ± 0.7 in the Winograd group, showing significant difference (P ＜ 0.05).

CONCLUSIONS

The lateral incision method without incising the nail fold reserves the nail groove and brings faster recovery to normal activities with less pain, lower infection rate and more satisfactory toenail shape.

Paronychia-like cutaneous leishmaniasis

Chronic paronychia is an inflammatory recalcitrant disorder affecting the nail folds. We report one patient with paronychia revealing ungueal leishmaniasis. A 34-year-old man, resident in the north of Morocco, presented with a 6-month history of an inflamed proximal nail fold of the left thumb, resistant to antibiotics and anti-fungal treatments. En bloc excision of the proximal nail fold was done. The histopathological exam showed epithelioid granulomas with giant cells and the presence of leshmania amastigotes, leading to the diagnosis of ungueal leishmaniasis. Clinical aspects of cutaneous leishmaniasis can be very misleading. The paronychial form is rarely described. In endemic areas it is necessary for the physician to be aware of atypical skin presentations of leishmaniasis.

Swiss roll technique for treatment of paronychia

Management of paronychia should primarily be aimed at preventing any activity that results in impairment of the natural barrier function of the nail fold. Surgical treatments aim to cure paronychia by exposing the inflamed germinal matrix to permit unrestricted drainage. We describe a Swiss roll technique for treatment of chronic and severe acute paronychia.

Acute and chronic paronychia

Paronychia is an inflammation of the folds of tissue surrounding the nail of a toe or finger. Paronychia may be classified as either acute or chronic. The main factor associated with the development of acute paronychia is direct or indirect trauma to the cuticle or nail fold. This enables pathogens to inoculate the nail, resulting in infection. Treatment options for acute paronychia include warm compresses; topical antibiotics, with or without corticosteroids; oral antibiotics; or surgical incision and drainage for more severe cases. Chronic paronychia is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. The patient should avoid exposure to contact irritants; treatment of underlying inflammation and infection is recommended, using a combination of a broad-spectrum topical antifungal agent and a corticosteroid. Application of emollient lotions may be beneficial. Topical steroid creams are more effective than systemic antifungals in the treatment of chronic paronychia. In recalcitrant chronic paronychia, en bloc excision of the proximal nail fold is an option. Alternatively, an eponychial marsupialization, with or without nail removal, may be performed.

Primäraffekt am Finger unter dem Bild einer chronischen Paronychie

A 33-year-old woman presented with a 4-months history of a granulating ulcer on the right index finger. Paronychia was suspected and nail extraction with subsequent histopathologic examination of the removed tissue was performed. Two months later, it became known that the patient's sexual partner had been treated for syphilis. The patient's serology was also positive. Subsequent examination of the original tissue sample by polymerase chain reaction, immunohistochemistry using Treponema pallidum-specific antibodies, and silver staining revealed large numbers of syphilis bacteria, confirming the diagnosis of extragenital chancre.

[Diagnosis and treatment of paronychia]

Paronychia is a purulent infection of the lateral fingertip, and represents the most common infectious disease affecting the hand.The typical germ is Staphylococcus aureus, while a mixture of bacteria or pathogens of a different kind are usually seen in patients with immunodeficiency. Treatment ranges from bathing the finger in an antiseptic solution to lancing the abscess.

En Bloc Excision of Proximal Nail Fold for Treatment of Chronic Paronychia

BACKGROUND

Chronic paronychia is a very recalcitrant dermatosis, which is particularly prevalent in housewives. Medical treatment for this condition is unsatisfactory in a significant number of cases. Surgical approach forms an important part of management, however, this area has received little attention. Various surgical approaches have been tried in the past but a comparative analysis has not been attempted.

OBJECTIVES

The present study aims at assessing the efficacy of en bloc excision of proximal nail fold (PNF). Moreover, a comparative analysis has been undertaken to assess whether or not simultaneous nail plate avulsion improves the treatment outcome.

METHODS

Thirty patients of chronic paronychia with nail plate irregularities were randomly divided into two treatment groups (15 patients each). After a detailed evaluation, en bloc excision of PNF with or without nail plate removal was performed. Postoperative measures were advised and the patients were kept under regular follow-up thereafter. Assessment of postoperative complications was also performed.

RESULTS

Twelve patients in group I and 13 patients in group II completed the treatment protocol. Of these, 70% of patients were cured in group II (en bloc excision with nail avulsion) whereas only 41% were cured in group I (en bloc excision without nail avulsion).

CONCLUSION

En bloc excision of the PNF is a useful method in recalcitrant chronic paronychia. Simultaneous avulsion of the nail plate improves the surgical outcome. Strict avoidance of irritant exposure is necessary to ensure complete treatment and prevent recurrence.

[Surgical therapy for hand infections. Part I]

Due to its function, anatomy, and exposition to multiple pathogens, the hand is highly susceptible to infection. Most of these infections are post-traumatic. Isolates of pathogens from infected hands contain mainly Staphylococcus aureus and beta-hemolytic group A streptococci. We find Pasteurella canis and P. multocida from cat and dog bite wounds and Eikenella corrodens from human bite wounds. The "fight-bite clenched fist" wound, with penetration of the metacarpophalangeal joint and its high risk of septic arthritis, has always to be suspected when patients present with human bites. The therapy of hand infection is based on three principles: surgical treatment, adequate antimicrobial therapy, and early physiotherapy. Early infectious conditions of the hand, e.g. cellulitis and early paronychia, may be treated without surgery. Antimicrobial treatment must be specific for the pathogen and its resistance to antimicrobial agents. Bite wounds should be treated with beta-lactam antibiotics and beta-lactamase inhibitors. Staphylococci and streptococci can be covered by first and second generation cephalosporins. The increasing resistance of staphylococci to antibiotics has to be taken into account. Infections with anaerobic and gas-producing bacteria are rare but occur predominantly in diabetics and immune-compromised individuals.

DAREJD simple technique of draining acute paronychia

The severe deformities of the fingers seen in poorly treated or late presenting cases of paronychia stimulated this prospective study. The aim was to make early diagnosis and to find a simple method of draining the pus in the paronychia. This was a prospective hospital based study at the Wesley Guild Hospital (WGH) Ilesa for 9 months. Using simple materials like 23G or 21G needle, cotton wool, chlorohexidine solution, methlylated spirit and zinc oxide plaster, abscess in acute paronychia was drained by lifting the nail fold with the tip of the needle. Ten cases of paronychia in 8 patients were drained with the method. Combination of the early drainage and antibiotics showed that all the patients were relieved of pain and could use their fingers normally within 2 days. There was no need of anesthesia and daily dressing. The drainage technique is simple and effective. The early drainage prevents the occurrence of any form of complication.

The effects of clonidine added to mepivacaine for paronychia surgery under axillary brachial plexus block

We hypothesized that onset of sensory block is delayed in infected versus healthy tissues within the same nerve distribution after axillary brachial plexus block (ABPB) and that clonidine added to mepivacaine would enhance anesthesia and postoperative analgesia. Forty-one outpatients undergoing thumb/index paronychia surgery under ABPB were randomly assigned to receive in a double-blind fashion 400 mg mepivacaine plus either 100 microg clonidine (clonidine group, n = 21) or 2 mL saline (placebo group, n = 20). Onset of sensory block in the infected area was delayed compared with healthy areas of the same nerve distribution (24.7 +/- 5.5 min versus 21.3 +/- 7.2; P = 0.02 for median and 21.6 +/- 7.8 min; P = 0.04 for radial) within the placebo group. In the clonidine group, when compared to placebo i) onset of sensory block in both the median and radial nerve territories was accelerated (11.1 +/- 5.6 and 10.5 +/- 5.2 versus 21.3 +/- 7.2 and 21.6 +/- 7.8 min, respectively; P < 0.001), ii) onset of sensory block in the region of infection was accelerated (9.1 +/- 1.9 versus 24.7 +/- 5.5 min; P < 0.001), iii) duration of anesthesia (275 +/- 75 versus 163 +/- 57; P = 0.04) and time to first analgesic requirement (279 +/- 87 versus 197 +/- 84 min; P = 0.002) were prolonged with decreased visual analog scale scores at this time (30 +/- 18 versus 70 +/- 24; P < 0.001), and iv) verbal numeric rating scores were decreased at 24 h (1.7 +/- 2.2 versus 4.1 +/- 3.0; P = 0.002) and 48 h (0.1 +/- 0.5 versus 1.5 +/- 2.4; P = 0.01) postoperatively. Our findings suggest that in the setting of distal infected tissue surgery under ABPB infected tissues are resistant to anesthesia compared with healthy areas within the same nerve distribution and clonidine added to mepivacaine enhances both anesthesia and postoperative analgesia.

Paronychia due to Prevotella bivia that resulted in amputation: fast and correct bacteriological diagnosis is crucial

Prevotella bivia is mainly associated with endometritis. The case of a patient with paronychia in a thumb due to P. bivia resulting in osteitis and amputation is reported. The species was not acknowledged in the first bacterial culture 2 weeks before surgery.

[A regenerative method for the surgical treatment of paronychia by applying a buried suture]

The suggested regenerative method for surgical treatment of panaritium with placing a blind suture at the period of formation of lipoblasts (at day 3 after the operative intervention) permits to prevent development of purulent complications, accelerate the process of wound healing within a period approximating that in wound healing by primary intention with complete restoration of the hand and digit function.

[The parenteral administration of terridecase in the treatment of suppurative-inflammatory diseases of the hand]

Patients with purulent inflammatory diseases were treated by parenteral administration of terrydecaza (polyglucin-immobilised terrylythin). It was noted that injections of terrydecaza facilitated the penetration of antibiotics to the purulent focus. The terms of cleansing the purulent wounds and transition of the inflammatory process to the second stage were 2-3 days shorter. The microcirculation was improved by the daily thermographic monitoring method. The increased penetration through the biological membranes was confirmed by higher concentration of middle weight molecules in plasma of the venous blood flowing off from the purulent focus.

Eponychial marsupialization and nail removal for surgical treatment of chronic paronychia

A long-term retrospective study of patients with chronic paronychia treated by eponychial marsupialization with or without nail removal is presented. Twenty-eight consecutive fingers with chronic paronychia in twenty-five patients were surgically treated. Symptoms had been present for 28 +/- 7 weeks. Twenty-three of these had nail irregularities. Of this group, the first seven fingers were treated with marsupialization alone. Recurrences developed in two of these. The next sixteen patients with nail irregularities were treated with marsupialization plus nail removal, and there were no recurrences (p less than 0.05). Furthermore, when the two recurrent paronychia were treated with both procedures, one healed completely and the other was markedly improved. All fingers without nail irregularities healed with marsupialization alone. These results confirm that eponychial marsupialization is an effective means of treating chronic paronychia and suggest that nail removal should be done when concurrent nail irregularities are seen.

The treatment of felons and paronychias

Infections of the distal finger have a varied presentation, course, and treatment. As in other hand infections, initial treatment should always include elevation of the extremity and the avoidance of snug clothing or constricting jewelry. Immunosuppressive states and systemic diseases such as diabetes must be considered, for they will alter the action of the causative organisms as well as the intensity of treatment that a patient will require. Appropriate, specific antibiotic treatment can be part of the initial treatment of acute felons and paronychias, but it should never replace adequate incision and drainage. Finally, "minor" finger infections are only minor when diagnosed and treated properly. If mistreated, their consequences can have long-term implications for both the individual and for society. It is important to understand the natural history, bacteriology, and anatomy of the distal finger if we are to return patients to their jobs with expedience and minimal long-term sequelae.

Hand complications in children from digital sucking

Digital sucking is common in children. Although orthodontic complications have been reported, hand complications of digital sucking are seldom described. Five patients are reported; two had digital deformities and three had infections. Deformities of the digits were improved with splinting. Infections required surgical drainage followed by postoperative splint protection to prevent digital sucking. Splinting prohibited sucking in four of five patients.

[Treatment of complicated forms of paronychia by using the electrophoresis of anti-inflammatory and antimicrobial preparations]

The work presents an analysis of treatment of patients with complicated forms of panaritium. To increase the efficiency of treatment the authors used certain physical factors, in particular, direct electric current--interstitial (intracavitary) electrophoresis of antimicrobial and antiinflammatory agents in complex therapy. The investigation of results of the treatment shows sufficiently high efficiency of the interstitial (intracavitary) electrophoresis. The time of treatment of patients with complicated forms of panaritium became 2 times shorter.

[Diagnosis and treatment of bone paronychia]

Examination and operations were made on 46 patients with bony panaritium. Early diagnosis of this disease along with X-ray examination were based on data of case histories of the patients and clinical symptoms. Surgical treatment included parsimonious dissection of necrotic tissues and suturing the wounds. In cases of large subcutaneous cavities drainage of the wound by perfusion with an antiseptic solution was used. Best results were obtained with the help of tamponage of the wound following removal of the altered tissues by a dry gauze turunda and a bath with the solution of potassium permanganate of feziamon.

[Operative treatment of osseous and osteoarticular paronychia by applying a closed suture to the wound and by prolonged intra-osseous administration of antibiotics]

Continuous intraosseous injections of antibiotics were used in 104 patients in the operative treatment of bony and osteo-articular panaritium with putting primary sutures on the wound. Healing by first intention was noted in most cases.

[Blind suture for paronychia in children]

From 1966 the author has been using the method of early surgical treatment of complicated forms of panaritium in order to remove the pyo-necrotic substrate and place primary sutures on the wound. The age of ninety children was from 1 year 8 month to 15. The primary suture provides better anatomical and functional results of treatment of panaritium in children and shortens the time of treatment.
