We report a method for removing the distal segment of a broken locked intramedullary nail secondary to nonunion of the femur following radiotherapy for fibromatosis. A Kirschner wire with one tip fashioned into a hook was used to remove the distal segment without opening with the nonunion site. Details of the procedure are described.
Sixty two patients with displaced femoral neck fractures treated by percutaneous pinning are reviewed. There were 37 females and 25 males with an average age of 63.7 years. There were 36 Garden grade III and 26 grade IV fractures. Twenty three patients had other medical conditions. Fourteen patients were operated under local anaesthesia. Superficial wound infection was found in three cases with no deep infection. Union occurred in 41 patients by eight months. Of the 21 non-unions 15 remained painless. The pins migrated outwards in seven cases but caused no clinical problem. Avascular necrosis was seen in 11 patients by 18 months. Avascular necrosis and non-union occurred together in six patients. Secondary hemiarthroplasty was performed in only ten patients. Routine hemiarthroplasty for femoral neck fractures is not always indicated. Femoral head preservation should be attempted before prosthetic replacement. The pinning surgery is simple, fast and can be performed under local anaesthesia. Hemiarthroplasty should be reserved for failed cases only.
Kawasaki disease is characterized by fever for ≥ five days, bilateral bulbar conjunctival injection without exudate, polymorphous rash changes in the extremities, oral mucosal changes, and cervical lymphadenopathy. We report a 20-month-old boy with Kawasaki disease who had onychomadesis affecting the fingernails and toenails bilaterally. To our knowledge, there were three reported cases of onychomadesis associated with Kawasaki disease, to which we add another one. We suggest keeping in mind the possibility of onychomadesis as a nail sequela of Kawasaki disease.
We describe a 6-year-old boy with an asymptomatic linear eruption on the left index finger with mild erythema of the proximal nail fold, nail dystrophy, and subungual hyperkeratosis of the nail. A diagnosis of nail lichen striatus was made. The child was successfully treated with a topical corticosteroid. Because of its rarity, nail lichen striatus is often under-recognized. Physicians should be familiar with the nail involvement in individuals with lichen striatus so that an accurate diagnosis can be made and unnecessary investigations and treatment avoided.
The Akaki River in the Upper Awash Basin, which flows through Addis Ababa, the capital city of Ethiopia, has been highly polluted by sewage from factories and residential areas. A population-based cross-sectional study was used to assess the association between trace elements and kidney injury from residents living in polluted areas downstream (Akaki-Kality) versus upstream (Gullele) in Sub-Cities of Addis Ababa. A total of 95 individuals (53 from Akaki-Kality and 42 from Gullele) were included in the study. Kidney injury molecule 1 (KIM-1), lead, arsenic, cadmium, cobalt, lead, manganese, zinc, iron, copper, chromium and nickel were evaluated in residents' urine and nail samples. A large proportion (74%) of the sample population contained KIM-1, including 81% residents in Akaki-Kality and 64% residents in Gullele. KIM-1 was, however, not significantly different (p = 0.05) between the two Sub-Cities, with median of 0.224 ng/mL in Akaki-Kality and 0.152 ng/mL in Gullele. Most of the analyzed elements, except Pb, As, Cd and Co, were found in all of the nail samples, with median (µg/g) in the range of 442‒714 Fe, 97.0‒246 Zn, 11.6‒24.1 Mn, 4.49‒5.85 Cu, 1.46‒1.66 Cr and 1.22‒1.41 Ni. The high incidence of KIM-1 indicates a potential for long term renal tubular damage among residents of the Sub-Cities. The concentrations of the elements in nails were, however, not significantly associated (p = 0.05) with the corresponding levels of KIM-1 in urine. Hence, the observed KIM-1 might be related to exposure to toxic substances or factors other than those included in this study.
A case of Stevens-Johnson syndrome induced by clindamycin resulting in total shedding of all the nails is reported to highlight the rarity and severity of the drug reaction.
Nail bed injuries were commonly found concomitantly with fingertip injuries. Reconstruction of fingertip including the nail bed should be attempted at acute stage. Aim of the surgery was to restore as much finger length and achieve normal nail growth. In chemical burns, the initial presentation might not reflect the exact extent of injury. Appropriate acute management must be initiated while waiting for demarcation. We report a case of young stewardess who presented with fingertip chemical burn injury. Surgical debridement was done on third day post-injury. A cross-finger flap to cover skin defect and split-thickness nail bed grafting from the remnant of injured finger were done. Excellent functional and cosmetic outcome was achieved in 6 months. Surgical treatment in a chemical burn was similar to traumatic injury. Nail bed graft was the best option for nail bed reconstruction. In cases of soft tissue loss, advancement or pedicle flaps are beneficial.
We have read the paper "Important tips and numbers on using the cortical step and diameter difference sign in assessing femoral rotation - Should we abandon the technique?" [1] with great interest. Restoring femoral rotation during intramedullary nailing can pose challenges to many experienced surgeons. Femur rotational side-to-side asymmetry which is greater than 10 ° will cause functional deficit. We propose a surgical technique which allows surgeons to evaluate and reduce the malrotated femur intraoperatively. This technique also improves the ergonomics of the surgery and can be used simultaneously with other femoral rotation evaluation techniques. LEVEL OF EVIDENCE: V.
Yellow nail syndrome (YNS) is an uncommon disorder characterized by a triad of nail dystrophy, lymphedema, and pleural effusion. It is rare in children and congenital occurrence of YNS has been very rarely described. We report a 2-year-old Arab boy having congenital yellow nail syndrome with mild facial dysmorphism and bilateral conjunctival pigmentation born to consanguineous parents. One of his older siblings had died of nonimmune fetal hydrops (NIFH). The case supports the genetic basis of yellow nail syndrome with a possible relationship to nonimmune fetal hydrops.
Aseptic non-union is a major problem following complicated fracture tibia, which carries significant morbidity and prolonged course of treatment. Plate fixation and autogenous bone grafting has been established as a method of treatment. However the risk of infection, implant failure and donor site morbidity are high. We reviewed twelve consecutive cases of established non-union tibia treated by closed reamed interlocking nail in our centre. All patients had clinical and radiological union at three months. Three patients were complicated with infection and one required removal of implant and re-reaming to eradicate infection. Reamed interlocking nailing is an alternative treatment for selected non-union of fracture tibia with promising results.
Exposure to toxic metals and excessive amount of trace elements is a risk factor of cognitive decline. Continuous monitoring of these elements by the use of metabolically inactive tissues such as fingernails may help in taking preventive measures to delay the cognitive decline process. In this study, the cognitive function of 54 elderlies (60-72 years old) from FELDA Sungai Tengi, Selangor, was evaluated using the Malay version of Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA). The levels of arsenic (As), cadmium (Cd), copper (Cu), manganese (Mn), lead (Pb), and zinc (Zn) in fingernail were detected using Inductively Coupled Plasma-Mass Spectrometry. Results showed that (92.6 %) our population was cognitively impaired based on the MoCA with mean score of 18.07 ± 5.11. The mean level of elements in fingernails for As, Cd, Cu, Mn, Pb, and Zn were 16.68 ± 3.52, 4.26 ± 0.91, 4.81 ± 1.16, 1.00 ± 0.23, 1.83 ± 0.47, and 40.86 ± 10.81 μg/g, respectively. Significant inverse correlations were observed between MoCA with age (r = -0.543, p
The treatment of displaced supracondylar fracture humerus (Gartland Type III) in children continues to be a challenging problem. We did a retrospective study of such fractures treated in Hospital Muar, over a 2 years period (from January 1998 to December 1999). A total of 42 cases with displaced supracondylar fractures, treated with open reduction and internal fixation were studied. All cases were operated using a posterior triceps splitting approach and crossed kirschner wires were used to stabilize the fracture site. An excellent outcome was seen in 34 patients (81%) and a good outcome in 7 patients (17%). The incidence of complications such as pin tract infection (14%), nerve injury (2%) was very low. None of the patients had vascular complications or myositis ossificans.
Ten patients with complex non-union of the tibia were treated by locked intramedullary nailing. These patients had scarred skin as a result of initial severe open fractures, multiple debridement or fasciotomies with external fixators and skin grafts applied. Seven of the patients also had previous osteomyelitis or pin track infections. Fully pain-free walking was achieved in all patients and radiological union in nine patients without the need for a bone graft. Four patients developed infection after nailing, of which three resolved with treatment.
This article describes the development of a partially degradable metal bone pin, proposed to minimize the occurrence of bone refracture by avoiding the creation of holes in the bone after pin removal procedure. The pin was made by friction welding and composed of two parts: the degradable part that remains in the bone and the nondegradable part that will be removed as usual. Rods of stainless steel 316L (nondegradable) and pure iron (degradable) were friction welded at the optimum parameters: forging pressure = 33.2 kPa, friction time = 25 s, burn-off length = 15 mm, and heat input = 4.58 J/s. The optimum tensile strength and elongation was registered at 666 MPa and 13%, respectively. A spiral defect formation was identified as the cause for the ductile fracture of the weld joint. A 40-µm wide intermetallic zone was identified along the fusion line having a distinct composition of Cr, Ni, and Mo. The corrosion rate of the pin gradually decreased from the undeformed zone of pure iron to the undeformed zone of stainless steel 316L. All metallurgical zones of the pin showed no toxic effect toward normal human osteoblast cells, confirming the ppb level of released Cr and Ni detected in the cell media were tolerable.
Once believed to be a rare disease in developed countries, recent data suggest that there is a surge in incidence of congenital syphilis in many developed countries. Diagnosis of congenital syphilis can be difficult because more than two-thirds of affected infants are asymptomatic at birth, and signs of symptomatic infants may be nonspecific or subtle. On top of this, some affected infants may have atypical presentations. Familiarity with the diverse presentations is essential to diagnosis. We report a 2-week-old male infant with congenital syphilis whose cutaneous manifestations included diffuse, erythematous keratoderma with desquamation and fissures on his hands and feet, multiple linear scaly fissures at the angles of his mouth, and onychauxis of the fingernails and toenails To our knowledge, diffuse, erythematous keratoderma of the hands and feet and thick nails have not been reported previously in congenital syphilis.
Onychomycosis is the infection of nail apparatus by dermatophytes, yeasts or non-dermatophyte moulds and is responsible for 50% of all nail disorders. A five year retrospective study was conducted at Universiti Kebangsaan Malaysia to identify the common pathogens responsible for onychomycosis and to describe the epidemiology of the affected patients. A total of 278 abnormal nails were cultured, out of which 231 were positive for fungus. Females constituted 50.2% (n=116) while males 49.8% (n=115). The majority (51.9%, n=120) were between ages 50-69 years. The Malay ethnic group was most commonly affected (44.2%, n=102) followed by Chinese (33.8%, n=78), Indians (18.2%, n=42) and other ethnic groups (3.8%, n=9). The most common fungal element isolated was non-dermatophyte moulds (45.4%, n=105) followed by yeast (34.6%, n=80) and dermatophytes (1.3%, n=3). Aspergillus spp. was the commonest (59.8%,n=81) non-dermatophyte mould, while Candida spp. was the commonest yeast (74.3%, n=89) isolated. In this study, non-dermatophyte moulds are the most common microorganisms implicated to cause onychomysosis. Treatment for non-dermatophyte mould is challenging as the current available antifungal agents are more effective against dermatophytes and yeasts.
Onychomycosis is a common nail disease with numerous etiological pathogens. In order to determine and trend the local mycological pattern of culture-positive diseased nail samples sent from the Department of Dermatology, Hospital Kuala Lumpur, a five-year retrospective audit was carried out, which revealed that non-dermatophyte molds were the predominant fungi isolated, followed by yeasts and dermatophytes. This is similar to two previous studies in Malaysia, but varies greatly from other studies around the world which showed a dermatophyte-predominant prevalence. This could be due to the nature of the environment our patients encountered.
The importance of bacteria-suspending media and fingertip positions on the survival of Vibrio cholerae on human fingertips were examined. Vibrios were suspended in phosphate-buffered saline (PBS), PBS with albumin, and PBS with agarose. Each type of preparation was inoculated on the fingerpads, the hyponychia, or the eponychia and lateral nail grooves of the fourth, third and second fingers of a volunteer's hand. The last finger inoculated was immediately washed with PBS and the washing collected for examination ("0 minute" exposure). The third and fourth inoculated fingers were likewise washed for examination 2 and 5 minutes later, respectively. The vibrios obtained from the washings were enumerated by culture. For each of the different groups, which consisted of a different inoculated fingertip position, bacteria-suspending medium and exposure period of 2 or 5 minutes, the proportion of replicate inoculated fingers which retained viable vibrios (isolation rate) and the mean number of surviving vibrios, as a percentage of the inoculated vibrios at "0 minute exposure" (survival rate) were as follows: finger pads: vibrios in PBS, 2 minutes post-inoculation (isolation rate, 25%; mean survival rate, 0.002%); 5 minutes post-inoculation (isolation rate, 0%; mean survival rate, 0%). PBS-albumin: 2 minutes post-inoculation (60%, 0.004%); 5 minutes post-inoculation (40%, 0.03%). PBS-agarose: 2 minutes post-inoculation (100%, 24%); 5 minutes post-inoculation (38%, 0.005%). Lateral nail grooves and eponychia: PBS: 2 minutes post-inoculation (100%, 2.2%); 5 minutes post-inoculation (44%, 0.2%). PBS-agarose: 2 minutes post-inoculation (100%, 32%); 5 minutes post-inoculation (100%, 0.7%). Hyponychia: PBS: 2 minutes post-inoculation (100%, 8%); 5 minutes post-inoculation (100%, 0.2%). PBS-agarose: 2 minutes post-inoculation (100%, 46%); 5 minutes post-inoculation (100%, 8%). The results show that vibrios in moisture-retaining medium (PBS-agarose) and inoculated on a sheltered fingertip locations (hyponychium) have the best survival rates. However, the high survival rate was maintained briefly.
Fractures of the femoral shaft treated with interlocking nails will ultimately result in breakage of the nail if the bone does not unite. Further management requires removal of the broken nail which may be a difficult process for the distal segment. If we can identify the symptoms just before the nail breaks, an exchange nailing becomes much easier. We present a patient with fibromatosis who underwent repeated surgery as well as radiotherapy at the age of 16. Six years later, she had a pathological fracture of the upper third of the femur for which an interlocking nail was inserted. The femur did not unite and the nail subsequently broke. Over a period of 12 years, three nails broke and had to be replaced. Two to 3 months before each breakage, the patient experienced the same set of symptoms for each episode. Knowing that her fracture was not going to heal will now alert us to do an exchange nailing before the nail broke again. It is well known that where there is evidence of non-union, pre-emptive treatment is necessary before implant failure.
KEY WORDS: Femur nonunion, interlocking nail, symptoms before breakage of nail.
