Focal hyperhidrosis can have a substantial influence on the professional, physical, emotional and social life of those affected. This becomes clear when the results of quality of life studies and Health Service Research studies are reviewed, e.g. affected patients were prepared to contribute additional money for treatment of hyperhidrosis. The systemic therapy of focal hyperhidrosis with oral anticholinergic agents is a quite economical treatment strategy. These products can be administered continuously or sporadically. However, only good clinical date for the continous treatment exists. Focal hyperhidrosis is a disease which requires our full attention. It should be discussed whether e.g. QoL questionnaires should be used routinelly.

Current published estimates of the prevalence of hyperhidrosis in the United States are outdated and underestimate the true prevalence of the condition. The objectives of this study are to provide an updated estimate of the prevalence of hyperhidrosis in the US population and to further assess the severity and impact of sweating on those affected by the condition. For the purposes of obtaining prevalence, a nationally representative sample of 8160 individuals were selected using an online panel, and information as to whether or not they experience hyperhidrosis was obtained. The 393 individuals (210 female, 244 non-Hispanic white, 27 black, mean age 40.3, SE 0.64) who indicated that they have hyperhidrosis were asked further questions, including body areas impacted, severity of symptoms, age of onset, and socioemotional impact of the condition. Current results estimate the prevalence of hyperhidrosis at 4.8 %, which represents approximately 15.3 million people in the United States. Of these, 70 % report severe excessive sweating in at least one body area. In spite of this, only 51 % have discussed their excessive sweating with a healthcare professional. The main reasons are a belief that hyperhidrosis is not a medical condition and that no treatment options exist. The current study's findings with regard to age of onset and prevalence by body area generally align with the previous research. However, current findings suggest that the severity and prevalence are both higher than previously thought, indicating a need for greater awareness of the condition and its associated treatment options among medical professionals.

A surprising palmar nevus: A case report

Full Text Available Raised palmar or plantar nevus especially in white people is an unusual feature. We present an uncommon palmar compound nevus in a 26-year-old woman with a large diameter (6 mm which had a collaret-shaped margin. In histopathologic evaluation intralymphatic protrusions of nevic nests were noted. This case was surprising to us for these reasons: size, shape, location and histopathology of the lesion. Palmar nevi are usually junctional (flat and below 3 mm diameter and intra lymphatic protrusion or invasion in nevi is an extremely rare phenomenon.

Full Text Available Background: Primary axillary hyperhidrosis (PAH is a chronic idiopathic disorder causing major stress in patients. Among the common therapies for PAH, only surgical interventions have proven feasible as a permanent solution. Objective and Aim: The aim of this study was to evaluate the efficacy and safety of fractional microneedle radiofrequency (FMR as an alternative permanent treatment for PAH with long-term follow-up. Materials and Methods: This was a single-blind, sham-controlled comparative study. Twenty-five patients with severe PAH were provided three treatments of FMR at 3-week intervals (the treatment group, and a control group was provided the sham treatment. Clinical efficacy was evaluated using the hyperhidrosis disease severity scale (HDSS at baseline and the end of the study, as well as during the 1 year follow-up phase. Results: HDSS demonstrated significant improvement after treatment in the treatment group compared to the sham control. The mean (±standard deviation of HDSS in the group being treated with radiofrequency was 2.50 (±0.88 after 1 year follow-up, and that of the control group was 3.38 (±0.49; P < 0.001. Follow-up results show that there were 10 patients (41.6% with no relapse and 11 patients (45.9% with relapse after 1 year. There was a significant correlation between HDSS changes in relapse and body mass index (BMI (P = 0.03. Conclusion: Treatment of PAH with FMR is a safe and noninvasive procedure with a positive therapeutic effect on HDSS. It is recommended, however, that sessions of FMR be repeated after 1 year, particularly in overweight patients with high BMIs. Clinical Trial Registration: IRCT2013111915455N1.

Yam, Andrew; Peng, Yeong-Pin; Pho, Robert Wan-Heng

2008-12-01

Soft tissue defects on the lateral borders of the digits are difficult to reconstruct using local or local-regional flaps. We describe a "palmar pivot flap" to resurface an adjacent defect on the palmar-lateral aspect of the digit. The surgical technique is described. This flap is an axial pattern flap based on the subcutaneous transverse branches of the digital artery. The flap is pivoted up to 90 degrees on the neurovascular bundle in its base, into an adjacent defect. The flap can be raised from either the proximal or the middle phalangeal segments. It can cover defects sited from the level of the proximal interphalangeal joint up to the fingertip. The donor defect is limited to the same digit and is covered with a full-thickness skin graft. We have used this flap on 3 patients with defects at the middle phalangeal segment, the distal interphalangeal joint, and the fingertip. All healed primarily. One patient had a mild flexion contracture of the proximal interphalangeal joint, whereas the other 2 had no complications. The patients with distal interphalangeal joint and fingertip defects had excellent sensation in the flap (2-point discrimination of 5-6 mm). The palmar pivot flap is useful for resurfacing otherwise difficult defects on the lateral borders of the digits around and distal to the proximal interphalangeal joint, including those at the fingertip. It provides sensate, glabrous skin. The donor defect is on the same digit and is well hidden, producing an aesthetic and functional reconstruction.

A 14-year-old girl and a 30-year-old woman presented with localised hyperhidrosis on the dorsal hand and wrist, respectively, provoked by different stimuli such as physical activity and minor trauma to the skin. The skin was seemingly normal in both patients where an iodine-starch test revealed...... a well-demarcated area of hyperhidrosis. Following histopathological examination, the diagnosis was unilateral localised hyperhidrosis in both cases; one with normal histology and one with a nevus sudoriferous. Both patients were successfully treated with botulinum toxin type A. The 30-year-old woman...... additionally used low-dose propantheline bromide periodically and experienced long-term remission on this therapy. Hyperhidrosis may embarrass and interfere with patients' school and careers, and it is therefore important to tailor an effective individual treatment....

Full Text Available Background: Primary axillary hyperhidrosis (PAH is a common condition with a great impact on the patient′s quality of life (QOL. It is associated with serious social, emotional, and occupational distress. The aim of this study was to investigate the QOL in patients with PAH before and after treatment with fractionated microneedle radiofrequency (FMR. Materials and Methods: We evaluated 25 patients with severe PAH. Each patient had three sessions of FMR treatment using a novel applicator at 3-week intervals. The study was based on Dermatology Life Quality Index (DLQI Questionnaires. Patients were evaluated at baseline and 3 months after the last session. Results: Our patients included 32% males and 68% females. The mean ± standard deviation (SD age of subjects was 30.2 ± 6.27 years. The mean ± SD of the DLQI before and after treatment was 12.96 ± 5.93, and 4.29 ± 2.21, respectively. There was a statistically significant difference between the before and after intervention (P < 0.001. No major, permanent adverse effects were shown. Conclusion: Treatment with FMR can improve the DLQI of patients with PAH.

The aim of the study was to evaluate the sympathectomy procedures for primary hyperhidrosis in terms of complications and effectiveness. From January 2010 to September 2012 we performed 130 sympathectomies in 65 patients, 27 males (42%) and 38 females (58%). Electrocoagulation was used in 20 procedures (15%), ultrasonic scalpel in 54 (42%), and radiofrequency dissector in 56 (43%). Seven patients (11%) underwent bilateral sympathectomy in the same surgical session, while in 58 (89%) the right surgical approach was delayed 30 days from the first procedure. We noticed 12 complications (9%): (a) chest pain in 6 patients (4 with electrocoagulation, 1 with ultrasonic scalpel, and 1 with radiofrequency dissector), which disappeared in 20 ± 1 day; (b) paresthesias in 3 electrocoagulation patients, was solved in 23 ± 5 days; (c) bradycardia in 1 ultrasonic patient, normalized in 4th postoperative hour; (d) unilateral relapse in 2 electrocoagulation patients after the second side approach, positively treated in 1 patient by resurgery in video-assisted thoracoscopy (VAT). The quality-adjusted life year and the quality of life evaluation revealed a statistically significant improvement (p = 0.02) in excessive sweating and general satisfaction after surgery, with Ultracision and LigaSure showing better findings than electrocoagulation. The latest generation devices offered greater efficacy in the treatment of hyperhidrosis, minimizing complications and facilitating the resumption of normal work and social activity of patients.

Palmar-plantar erythrodysesthesia secondary to docetaxel chemotherapy: a case report

Directory of Open Access Journals (Sweden)

Al-Niaimi Amjad

2011-02-01

Full Text Available Abstract Introduction Docetaxel is a chemotherapeutic agent used alone or in combination for the management of many neoplastic conditions. Numerous side effects are well described as a consequence. Palmar-plantar erythrodysesthesia, although a relatively common side effect of some types of chemotherapy, occurs infrequently with docetaxel and is often attributed to other drug agents. Case Presentation We report the case of a 66-year-old Caucasian woman who received adjuvant docetaxel monotherapy for invasive breast cancer. She developed palmar-plantar erythrodysesthesia following her first cycle of treatment, which necessitated a change in management. Conclusion Palmar-plantar erythrodysesthesia is a relatively common side effect of cytotoxic chemotherapy, particularly with drugs such as 5-fluorouracil, capecitabine and liposomal doxorubicin. Docetaxel is commonly used both alone and in combination with a number of these agents for the management of various malignant conditions. We would like to highlight the occurrence of palmar-plantar erythrodysesthesia as a result of docetaxel monotherapy so that it can be considered as a potential cause in patients receiving combination treatment with chemotherapeutic agents better known to cause this toxicity.

Elevated concentrations of doxorubicin are found in eccrine sweat glands of the palms and soles. We therefore evaluated an antiperspirant as preventive treatment for palmar-plantar erythrodysesthesia (hand-foot syndrome) in patients with metastatic breast cancer treated with pegylated liposomal doxorubicin. An antiperspirant containing aluminum chlorohydrate or placebo cream was applied to the left or right hand and foot in a double-blinded manner (intra-patient randomization). The primary endpoint was the rate of grade 2 or 3 palmar-plantar erythrodysesthesia. A secondary endpoint was the patient-reported symptom burden (tingling, numbness, pain, or skin problems). Using McNemar's matched pairs design, 53 patients were needed to detect a 20% difference between the treatment and placebo sides with a significance level of 5% and power of 90%. Grade 2 or 3 PPE occurred in 30 (58%) of 52 evaluable patients; in six patients adverse effects occurred on the placebo side but not on the treatment side, whereas one patient developed palmar-plantar erythrodysesthesia on the treatment side only (P = 0.07). Four patients developed grade 2 or 3 palmar-plantar erythrodysesthesia on their foot on the placebo side but not on the treatment side (P = 0.05). In the cohort with grade 2 or 3 palmar-plantar erythrodysesthesia there was a trend towards fewer dermatologic symptomatologies with the active treatment (P = 0.05), and no difference for other adverse events. Using topical aluminum chlorohydrate as an antiperspirant appears to reduce the incidence of grade 2 or 3 palmar-plantar erythrodysesthesia following pegylated liposomal doxorubicin chemotherapy for metastatic breast cancer.

Full Text Available Studies on children with hyperhidrosis are sparse. This retrospective study presents clinical data and quality of life, along with treatment effect and safety of botulinum toxin (BTX. Case reports from 366 children were included to capture the medical history of hyperhidrosis. The total median score of the Dermatology Life Quality Index before treatment was 11 for children aged 16–17 years and 12 for children younger than 16 years. The children described physical, psychosocial and consequence-related symptoms. More than 70% had multifocal hyperhidrosis. BTX-A and/or BTX-B were given to 323 children, 193 of whom received repeated treatments. The highest score in a 5-grade scale concerning treatment effect was reported by 176/193 children, i.e. their “sweating disappeared completely”. No severe adverse events occurred. Focal and multifocal hyperhidrosis in children reduces quality of life considerably. Treatment with BTX-A and/or BTX-B has been performed with success.

2006-06-01

Circumscribed palmar or plantar hypokeratosis is a rare dermatosis characterized by a solitary, well-circumscribed patch with scaly borders chiefly on the palm or sole; it usually occurs in middle-aged or elderly women. We report the case of a 52-year-old Korean woman with two characteristic lesions of circumscribed palmar hypokeratosis on the left palm. Clinically, the lesions simulated porokeratosis of Mibelli, but histologically there was no cornoid lamellation in the serial sections and there were the characteristic histopathological features of circumscribed palmar or plantar hypokeratosis including a stair-like configuration with an abrupt thinning of the stratum corneum and a decreased granular layer. We also review the 16 cases of circumscribed palmar or plantar hypokeratosis reported in the published work.

Full Text Available Compound palmar ganglion, or chronic flexor tenosynovitis, most commonly of tuberculousorigin, is a rare extrapulmonary manifestation of tuberculosis (TB. The flexor synovialsheath is not a common site for TB but, once involved, causes rapid involvement of all flexortendons. We discuss the case of a 70-year-old farmer who presented to us with pain and progressive swelling of the palmar aspect of the wrist. On clinical examination, swelling both above and below the proximal wrist crease was found, with positive cross-fluctuation. Onultrasonography and magnetic resonance imaging, features suggestive of compound palmarganglion were present. The patient underwent surgical resection (extensive tenosynovectomyand chemotherapy. Post-operative histopatholgical findings correlated with the radiological features.

Erosion of the palmar (flexor) aspect of the navicular bone is difficult to diagnose with conventional imaging techniques. To review the clinical, magnetic resonance (MR) and pathological features of deep erosions of the palmar aspect of the navicular bone. Cases of deep erosions of the palmar aspect of the navicular bone, diagnosed by standing low field MR imaging, were selected. Clinical details, results of diagnostic procedures, MR features and pathological findings were reviewed. Deep erosions of the palmar aspect of the navicular bone were diagnosed in 16 mature horses, 6 of which were bilaterally lame. Sudden onset of lameness was recorded in 63%. Radiography prior to MR imaging showed equivocal changes in 7 horses. The MR features consisted of focal areas of intermediate or high signal intensity on T1-, T2*- and T2-weighted images and STIR images affecting the dorsal aspect of the deep digital flexor tendon, the fibrocartilage of the palmar aspect, subchondral compact bone and medulla of the navicular bone. On follow-up, 7/16 horses (44%) had been subjected to euthanasia and only one was being worked at its previous level. Erosions of the palmar aspect of the navicular bone were confirmed post mortem in 2 horses. Histologically, the lesions were characterised by localised degeneration of fibrocartilage with underlying focal osteonecrosis and fibroplasia. The adjacent deep digital flexor tendon showed fibril formation and fibrocartilaginous metaplasia. Deep erosions of the palmar aspect of the navicular bone are more easily diagnosed by standing low field MR imaging than by conventional radiography. The lesions involve degeneration of the palmar fibrocartilage with underlying osteonecrosis and fibroplasia affecting the subchondral compact bone and medulla, and carry a poor prognosis for return to performance. Diagnosis of shallow erosive lesions of the palmar fibrocartilage may allow therapeutic intervention earlier in the disease process, thereby preventing

The relative sensitivity of radiography, computed tomography, and magnetic resonance imaging for detecting palmar process fractures of the distal phalanx in foals was determined and the imaging findings were compared with histomorphologic evaluations of the palmar processes. Compared to radiography, computed tomography and magnetic resonance imaging did not improve the sensitivity for detection of palmar process fractures. Statistical agreement for palmar process fracture diagnosis was excellent among the three imaging modalities. Histomorphologic evaluations were more sensitive for diagnosis of palmar process fracture than any of the imaging modalities. Three-dimensional image reconstructions and volume measurements of distal phalanges and palmar process fracture fragments from computed tomography studies provided more complete anatomical information than radiography. Magnetic resonance imaging confirmed that the deep digital flexor tendon insertion on the distal phalanx is immediately axial to the site where palmar process fractures occur, and differentiated cartilage, bone, and soft tissue structures of the hoof

This case study details the unusual clinical findings in a unique paw-pad disorder that recently emerged among 2 male and 1 female naïve purpose-bred beagle dogs (Canis familiaris) newly received into our facility. During acclimation period physical examinations, the affected dogs demonstrated constantly moist, soft paw pads on all 4 feet. No information was available regarding the epidemiology and pathogenesis of this pad condition in beagle dogs. Here, we report the results of physical examination, clinical chemistry analysis, hematology, histopathology, detailed observations, and novel testing techniques performed during the acclimation period. Histopathology of several sections of affected footpads was compared with that of an age-matched dog with clinically normal paw pads. We describe the morphologic features of a distinctive cutaneous canine footpad condition and discuss the possible differential diagnoses. The histologic and clinical features were most consistent with those of hyperhidrosis; to our knowledge, this report is the first description of hyperhidrosis as a distinct condition in purpose-bred beagle dogs.

First suggested by Brent in 1979, the pocket principle is an alternative method for patients for whom a microsurgical replantation is not feasible. We report the successful results of a modified palmar pocket method in adults. Between 2004 and 2008, we treated 10 patients by nonmicrosurgical replantation using palmar pocketing. All patients were adults who sustained a complete fingertip amputation from the tip to lunula in a digits. In all of these patients, the amputation occurred due to a crush or avulsion-type injury, and a microsurgical replantation was not feasible. We used the palmar pocketing method following a composite graft in these patients and prepared the pocket in the subcutaneous layer of the ipsilateral palm. Of a total of 10 cases, nine had complete survival of the replantation and one had 20% partial necrosis. All of the cases were managed to conserve the fingernails, which led to acceptable cosmetic results. A composite graft and palmar pocketing in adult cases of fingertip injury constitute a simple, reliable operation for digital amputation extending from the tip to the lunula. These methods had satisfactory results.

2017-06-01

Fingertip amputation in children is difficult to manage using microsurgical replantation techniques and many salvage procedures have failed owing to the nonavailability of suitable veins for anastomosis in the fingertip. This study reviewed our experience of pediatric fingertip replantation involving palmar venous anastomoses and evaluated the clinical outcomes. From October 2008 to May 2013, 21 pediatric fingertips that had been completely amputated at or distal to the distal interphalangeal joint of the finger, or at or distal to the interphalangeal joint of the thumb were managed using complete replantation. One artery was anastomosed for revascularization with or without nerve repair, and a palmar venous anastomosis was performed to reestablish the outflow system. Twenty (95.2%) of the 21 fingertips survived. One replant involving an avulsion amputation of the left little finger failed, and the patient underwent stump cap-plasty. Excellent restoration of finger motion, pinch strength, and appearance was observed during the mean 39.9-month (range, 18-65 months) follow-up. The mean regained static 2-point discrimination sensation was 3.8 mm (range, 3.2-4.2 mm). All of the children and their families were satisfied with the surgical outcomes. Successful palmar venous anastomosis appears to promote the survival of replanted fingertips in children. Given that the procedure may simplify postoperative care, minimize complications, and achieve a high survival rate, it should be attempted if the technical expertise is available.

To evaluate the abnormalities and variations of the arterial system of upper extremities and superficial palmar arch with computed tomography angiography and to guide the clinician during this procedure. A total of 156 upper extremities of 78 cases were retrospectively analyzed using computed tomography angiography. The study was approved by the local ethics committee of the hospital. From the analysis of the computed tomography angiography images, the following information was recorded; the diameters and abnormalities of radial, ulnar and brachial arteries in both upper extremities, the presence of atherosclerotic changes or stenosis in these arteries, whether the superficial palmar arch was complete or incomplete, and arterial dominance. Also, the computed tomography angiography classification of superficial palmar arch distribution and anatomic configuration was performed. The mean baseline diameters of the radial, ulnar and brachial arteries of the cases were; 2.8 ± 0.6, 2.5 ± 0.7, and 4.7 ± 0.6 mm, respectively. A complete superficial palmar arch was observed in 69.2 % of the right hands and 70.5 % of the left hands. For the superficial palmar arches on the right side, the radial artery was dominant in two and the ulnar artery was dominant in 47 with the remaining showing codominance. On the left side, the radial artery was dominant in one hand, with the ulnar artery being dominant in 49 cases, and in 28 cases, there was codominance. In the superficial palmar arch classification, four of the arches (A-D) were defined as complete and the remaining three (E-G) as incomplete. The current study clarified different variations in palmar circulation and forearm arteries to aid the surgeon during trans-radial or trans-ulnar catheterization, hemodialysis, or coronary artery bypass grafting.

Developmental morphology of the forelimb distal phalanges and lateral palmar processes of 9 Thoroughbred foals aged 3–32 weeks was assessed using radiography, microradiography and histology. For inclusion in the study, all distal phalanges had no pathologic radiographic abnormalities.Vascular channels that are characteristically found in the dorsal region of the distal phalanx were not evident radiographically in the palmar process. The proximal and distal angles of the palmar processes were separated by a lucent line continuous with the incisure in foals only through 12 weeks of age. The distal phalanges were triangular-shaped in foals 3–12 weeks of age, and were oval-shaped in older foals.The palmar aspect of the distal phalanx was the major contributor to growth of the distal phalanx in the sagittal plane, especially between 3 and 12 weeks of age. Growth of the lateral palmar process occurred through the means of endochondral ossification. The body and cortices of the lateral palmar process were composed of coarse cancellous bone. Porosity within the lateral palmar process was greater in regions sampled axial, compared to abaxial, to the parietal sulcus and did not change with age.A fracture was identified microradiographically and/or histologically in 9 of 18 (50%) and 10 of 17 (59%), respectively, of the lateral palmar processes examined. The fracture line was consistently associated with the parietal sulcus on the dorsal cortical surface and was always immediately abaxial to the deep digital flexor tendon attachment. No age-related morphological changes of the lateral palmar processes were identified with microradiography or histological examinations

Recent studies on the etiopathogenesis of multiple sclerosis (MS) all point out that there is a polygenetical predisposition for this illness. The so called "MS Trait" determines the reactivity of the immunological system upon ecological factors. The development of the glyphological science and the study of the characteristics of the digito-palmar dermatoglyphic complex (for which it was established that they are polygenetically determined characteristics) all enable a better insight into the genetic development during early embriogenesis. The aim of this study was to estimate certain differences in the dermatoglyphics of digito-palmar complexes between the group with multiple sclerosis and the comparable, phenotypically healthy groups of both sexes. This study is based on the analysis of 18 quantitative characteristics of the digito-palmar complex in 125 patients with multiple sclerosis (41 males and 84 females) in comparison to a group of 400 phenotypically healthy patients (200 males and 200 females). The conducted analysis pointed towards a statistically significant decrease of the number of digital and palmar ridges, as well as with lower values of atd angles in a group of MS patients of both sexes. The main discriminators were the characteristic palmar dermatoglyphics with the possibility that the discriminate analysis classifies over 80% of the examinees which exceeds the statistical significance. The results of this study suggest a possible discrimination of patients with MS and the phenotypically health population through the analysis of the dermatoglyphic status, and therefore the possibility that multiple sclerosis is genetically predisposed disease.

Full Text Available O artigo buscou fazer uma releitura de Zumbi dos Palmares sob o prisma da resiliência, demonstrando uma visão singular ao olhar para os escravos nos quilombos e suas histórias de superação e transformação perante as adversidades, levando não só a reconstruir o imaginário afrodescendente brasileiro com o caleidoscópio da resiliência, mas revelar que a resiliência sempre foi inerente a história dos negros no Brasil. Para tanto se caracterizou como uma pesquisa exploratória com abordagem qualitativa e procedimentos bibliográficos que foram essenciais para a construção do artigo, amadurecendo e ampliando os conhecimentos envolvidos na temática. Nesta abordagem o quilombo dos Palmares foi um conjunto complexo de condições, atitudes e ações que apesar das adversidades tiveram resultados positivos, os fatos demonstraram que os negros nos quilombos foram uma prova que a resiliência negra não foi apenas um fator individual, mas uma característica comunitária que desencadeou um processo de ruptura e recuperação social, um grito de liberdade em defesa da consciência de uma raça, e de um povo. Zumbi não foi apenas um líder de um movimento libertário que marcou a história dos negros oriundos de Pernambuco e Alagoas, mas a história de uma raça por gerações no país, que se tornou sinônimo de resiliência.

Radiographic and pathologic characterization of lateral palmar intercarpal ligament avulsion fractures in the horse.

Beinlich, Christopher P; Nixon, Alan J

2004-01-01

In this study, the radiographic and histologic appearance of lateral palmar intercarpal ligament (LPICL) avulsion in the horse was characterized. Thirty-seven horses with radiographic evidence of avulsion fragments originating from the medial palmar aspect of the ulnar carpal bone were examined. The dorsolateral to palmaromedial projection was useful for evaluating the size and shape of the avulsed bone fragment, and the dorsopalmar projection added information on the relative proximity of the fragment to its fracture bed. Radiographic features that differentiated LPICL avulsion from subchondral cystic lesions of the ulnar carpal bone included a variable-sized osseous opacity adjacent to the lucent concavity of the fracture bed and the consistent location within the palmar transition zone at the confluence of LPICL insertion and hyaline cartilage on the palmar surface of the ulnar carpal bone. All 26 horses having surgical removal of the fragments had arthroscopic confirmation that the fragment was within the LPICL. Histologic examination confirmed the fragments were fracture related rather than developmental or the result of dystrophic mineralization. Many of the fragments had attached remnants of a ligament. This study describes the radiographic, surgical, and histologic features in 37 horses which better characterize LPICL avulsion fracture in the carpus and provide differentiating features to assist in separating this syndrome from true osseous cyst-like lesions within the ulnar carpal bone.

Full Text Available Background First suggested by Brent in 1979, the pocket principle is an alternative methodfor patients for whom a microsurgical replantation is not feasible. We report the successfulresults of a modified palmar pocket method in adults.Methods Between 2004 and 2008, we treated 10 patients by nonmicrosurgical replantationusing palmar pocketing. All patients were adults who sustained a complete fingertip amputationfrom the tip to lunula in a digits. In all of these patients, the amputation occurred due to a crushor avulsion-type injury, and a microsurgical replantation was not feasible. We used the palmarpocketing method following a composite graft in these patients and prepared the pocket in thesubcutaneous layer of the ipsilateral palm.Results Of a total of 10 cases, nine had complete survival of the replantation and one had20% partial necrosis. All of the cases were managed to conserve the fingernails, which led toacceptable cosmetic results.Conclusions A composite graft and palmar pocketing in adult cases of fingertip injuryconstitute a simple, reliable operation for digital amputation extending from the tip to thelunula. These methods had satisfactory results.

Full Text Available Leg amputees who can’t use prostheses and patients with arthritis are often dependent on crutches. Their chronic use can exert significant friction forces. The palmar skin will respond by forming a hyperkeratotic callus. We report for the first time unilateral palmar callus formation caused by friction from using crutches. Another possible adverse effect is the triggering of irritant contact dermatitis by the handholes of crutches. We report two cases with hand dermatitis due to the chronic dependence on crutches and discuss treatment options.

Lang, Hayley M; Nixon, Alan J

2015-05-01

To characterize discrete palmar carpal osteochondral fragmentation in horses and to document the effect of osteoarthritis and surgical removal of these fragments on functional outcome. Retrospective case series. 25 horses. Medical records and radiographic views were reviewed to identify horses that had radiographic evidence of palmar carpal fragmentation, which was subsequently treated by arthroscopic removal. Information collected included cause of fracture, initial and long-term clinical and radiographic findings, and functional outcome. Palmar carpal fragmentation of 30 carpal bones was identified in 25 unilaterally affected horses. A known traumatic event was reported to cause the fragmentation in 17 of the 25 (68%) horses. Of the 25 horses, 17 (68%) had fragmentation involving the antebrachiocarpal joint, 7 (28%) had fragmentation involving the middle carpal joint, and 1 (4%) had fragmentation involving the carpometacarpal joint. The proximal aspect of the radial carpal bone was the most commonly affected site (12/30 fragments), followed by the accessory carpal bone (6/30). Of the 25 horses, 19 (76%) were not lame (sound) after surgery and returned to their intended use, 4 (16%) were considered pasture sound, and 2 were euthanized (because of severe postoperative osteoarthritis or long bone fracture during recovery from anesthesia). Eight of the 14 horses with preoperative evidence of osteoarthritis returned to function after surgery. Twelve of 17 horses with antebrachiocarpal joint fragments and 6 of 7 horses with middle carpal joint fragments returned to their previous use. Results indicated that the prognosis for horses after arthroscopic removal of palmar carpal osteochondral fragments is good. Early intervention, before the development of osteoarthritis, is recommended.

creciente el número de procedimientos. La introducción de la videotoracoscopia mejoró la técnica, redujo la morbidad, el tiempo quirúrgico y el tiempo de permanencia hospitalaria. El adecuado manoseo anestésico, monitorización continuada y las técnicas a disposición permiten que el procedimiento sea realizado con seguridad o se modifiquen las conductas de acuerdo con las observaciones clínicas y las respuestas del paciente a las alteraciones dinámicas consecuentes de la cirugía y terapéutica farmacológica. Sería entonces, deber del anestesiologista disponer con criterio y buen sentido de las alternativas disponibles para asegurar al paciente un procedimiento seguro, una recuperación rápida con la menor morbidad posible.BACKGROUND AND OBJECTIVES: Primary hyperhydrosis is a disorder characterized by excessive diffuse or localized sweating. There are several noninvasive therapeutic methods which in general do not solve the problem generating even more anxiety, and time and money wasting for hyperhydrosis patients. Partial thoracic sympathetic chain resection is indicated for palmar hyperhydrosis and may be performed by thoracoscopic surgery with good results and few complications. This review aimed at discussing possible anesthetic techniques for this procedure, as well as possible complications and their management. CONTENTS: It is estimated that the incidence of primary hyperhydrosis varies from 0.6% to 1%, being more frequent in young patients. While in most cases axillary and plantar sweating causes discomfort only, excessive palmar sweating causes social, professional and psychological problems. Thoracoscopic sympathectomy has been performed in several hospitals and is increasing in number. Unless there are specific counterindications, bilateral sympathectomy is performed under general anesthesia through a double or single lumen catheter, with or without intrapleural carbon dioxide inflation. Major postoperative cares are early pneumothorax or residual

We developed a new triangular fibrocartilage complex reconstruction technique for distal radioulnar joint instability in which the palmar portion of the triangular fibrocartilage complex was predominantly reconstructed, and evaluated whether such reconstruction can restore stability of the distal radioulnar joint in seven fresh cadaver upper extremities. Distal radioulnar joint instability was induced by cutting all soft-tissue stabilizers around the distal ulna. Using a palmar approach, a palmaris longus tendon graft was sutured to the remnant of the palmar radioulnar and ulnocarpal ligaments. The graft was then passed through a bone tunnel created at the fovea and was sutured. Loads were applied to the radius, and dorsopalmar displacements of the radius relative to the ulna were measured using an electromagnetic tracking device in neutral rotation, 60° supination and 60° pronation. We compared the dorsopalmar displacements before sectioning, before reconstruction and after reconstruction. Dorsopalmar instability produced by sectioning significantly improved in all forearm positions after reconstruction.

Araújo, Rogério Gayer Machado de; Kouyoumdjian, João Aris

Temperature is an important and common variable that modifies nerve conduction study parameters in practice. Here we compare the effect of cooling on the mixed palmar median to ulnar negative peak-latency difference (PMU) in electrodiagnosis of carpal tunnel syndrome (CTS). Controls were 22 subjects (19 women, mean age 42.1 years, 44 hands). Patients were diagnosed with mild symptomatic CTS (25 women, mean age 46.6 years, 34 hands). PMU was obtained at the usual temperature, >32 degrees C, and after wrist/hand cooling to PMU and mixed ulnar palmar latency in patients versus controls. We concluded that cooling significantly modifies the PMU. We propose that the latencies of compressed nerve overreact to cooling and that this response could be a useful tool for incipient CTS electrodiagnosis. There was a significant latency overreaction of the ulnar nerve to cooling in CTS patients. We hypothesize that subclinical ulnar nerve compression is associated with CTS.

Incomplete longitudinal fracture of the proximal palmar cortex of the third metacarpal bone in horses

International Nuclear Information System (INIS)

Ross, M.W.; Ford, T.S.; Orsini, P.G.

1988-01-01

Seven horses, 2 to 4 years of age, were examined because of moderate-to-severe forelimb lameness, mild effusion of the middle carpal joint (3 horses), and pain on palpation of the origin of the suspensory ligament (4 horses). The lameness was abolished by anesthetic infiltration of the middle carpal joint in six horses. In four of them, a high palmar nerve block also abolished the lameness. A linear radiolucency in the proximal end of the third metacarpal bone (McIII) was interpreted as an incomplete longitudinal fracture. In one horse, distinct intramedullary sclerosis limited to the palmar cortex was indicative of an incomplete fracture confined to the palmar cortex. No osteoproliferative lesions were identified on the dorsal cortex of any of the horses. Surgical treatment with cortical screws in lag fashion accompanied by a rest period was successful in one horse. In four horses, rest for at least 3 months resulted in clinical soundness. In two horses, a shorter rest period resulted in recurrence of the lameness even though the horses were sound when put back into training. Careful clinical and radiographic examinations helped differentiate incomplete longitudinal fractures from lesions involving the carpus and proximal aspect of the suspensory ligament

The purpose of this study was to compare the results of fingertip replantations without (artery anastomosis only replantations) and with venous anastomosis (replantations in which both arterial and palmar venous anastomoses were performed). Also, distribution of the veins used for anastomosis was analyzed retrospectively. First 53 digits (47 patients) received only arterial anastomosis (group 1). For relieving venous congestion, external bleeding method was used. Last 41 digits (38 patients) received both arterial and palmar venous anastomoses without external bleeding (group 2). There was statistical significance of the survival rate between group 1 [77.3% (41/53)] and group 2 [92.6% (38/41)] (P = 0.039). Venous congestion was encountered at 10 digits in group 1 (all underwent necrosis totally) and at 3 digits in group 2 (both were moderate and could be salvaged partially) (P = 0.094, no statistical significance). There was statistical significance of the mean operation time for single-fingertip replantation between group 1 (80 ± 7.8 minutes) and group 2 (105 ± 14.5 minutes) (P replantations with palmar venous anastomosis have simpler postoperative care and lower drawbacks as compared with artery anastomosis-only replantations.

Cerebral palsy is one of the main causes of severe disability in children. Sixty children (30 boys and 30 girls) were included in the study. Quantitative digito-palmar dermatoglyphic traits were analyzed. Prints of digito-palmar dermatoglyphs obtained from the children's parents (60 mothers and 60 fathers) and from 400 phenotypically healthy adults from the Zagreb ware used as control groups. Analysis of quantitative dermatoglyphic traits of the digito-palmar complex revealed statistically significant differences in a number of variables between the fathers and their children suffering from cerebral palsy (TRC 180.3 > 158.6), with a greater number of variables involved in male children with cerebral palsy. Some variables showed statistically significant differences in dermatoglyphic patterns between fathers and control group of healthy males as well as between boys with cerebral palsy and healthy control males. Differences in dermatoglyphic patterns were significantly lower between mothers and girls with cerebral palsy (TRC 152.1 mothers and healthy control females. Study results support the hypothesis on the possible role of genetic predisposition in the occurrence of central nervous system lesion, with a more pronounced paternal impact.

2018-01-01

Intra-articular distal radius fractures have long been massively discussed in the literature, but regarding to fractures that possess rotated volar medial fragment in the joint a few amount papers has been written. In this article, we would like to emphasize the significance of the rotated palmar medial (lunate facet) fragment. A 39-year-old man fell from a height of about 3 m and landed on his right outstretched hand; within 40 min, he arrived at our clinic presenting with a severe pain and swelling in his right wrist. Initial X-rays of the wrist revealed dorsal subluxation of the radiocarpal joint with dorsal comminution of the radial articular surface and fracture of the radial styloid process, with (nearly inverted) ~ 140-150° rotation of the palmar medial fragment. With an additional volar approach, the fragment reduced and stabilized with two K-wires and wrist immobilized in external fixator. The patient returned to daily activities without any discomfort and pain after the 1 year from the surgery. Overlooking of palmar rotated osteochondral fragment will cause deficiency to build proper pre-operative strategy to approach the reduction of the fragment. The incompetence of reduction will deteriorate the articular surface and lead to early osteoarthritis of the wrist. The surgeon should detect this fragment and should be familiar with volar approaches of the wrist. Above average surgical experience would be needed for successful reduction.

Circumscribed palmar hypokeratosis (CPH) is a rare skin disease, first described in 2002, associated with sudden localized reduction of the corneal layer. In most cases, it presents as an isolated rounded erythematous palmar lesion on the thenar eminence. We describe the dermoscopic semiology of CPH in 3 cases. Three patients between the ages of 59 and 72 presented very limited erythematous lesions suggestive of CPH. Dermoscopic examination of these lesions provided similar findings. Biopsy, which was performed in one patient, confirmed the diagnosis of CPH. Two dermoscopic elements of CPH are characteristic: (1) the sides of the lesion have a "stair step" or "geological strata" type of configuration, and the thickness of the different strata varies; (2) the centre of the lesion showed a homogeneous erythematous area with a vascular pattern composed of dotted vessels of the superficial dermis and sometime vascular loops. These dermoscopic aspects are characteristic and enable CPH to be differentiated from Bowen's disease or porokeratosis of Mibelli. In Bowen's disease, there is no stair step like aspect to the sides of lesions; further, the centre of the lesion shows glomerular vessels (coiled vessels) and/or globular vessels (small red clods). In porokeratosis, peripheral keratotic "white track" structures comprise a single pigmented channel or a double white line. There is no "stair step" or central vascular pattern. The dermoscopic semiology of CPH is highly characteristic and enables differentiation from Bowen's disease and porokeratosis. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Wei, Ching-Yueh; Orozco, Oscar; Vinagre, Gustavo; Shafarenko, Mark

2017-11-01

Refinements in microsurgery have made distal finger replantation an established technique with high success rates and good functional and aesthetic outcomes. However, it still represents a technically demanding procedure due to the small vessel caliber and frequent lack of vessel length, requiring the use of interpositional venous grafts in some instances. We describe a new technique for anastomosis in fingertip replantation, whereby the need for venous grafts is eliminated. Applying the reverse distal transverse palmar arch technique, 11 cases of distal digital replantation were performed between January 2011 and July 2016. The described procedure was used for arterial anastomosis in 10 cases and arteriovenous shunting for venous drainage in 1 case. A retrospective case review was conducted. The technical description and clinical outcome evaluations are presented. Ten of the 11 replanted digits survived, corresponding to an overall success rate of 91%. One replant failed due to venous insufficiency. Blood transfusions were not required for any of the patients. Follow-up (range, 1.5-5 months) revealed near-normal range of motion and good aesthetic results. All of the replanted digits developed protective sensation. The average length of hospital admission was 5 days. All patients were satisfied with the results and were able to return to their previous work. The use of the reverse distal transverse palmar arch is a novel and reliable technique in distal digital replantation when an increase in vessel length is required, allowing for a tension-free arterial repair without the need for vein grafts.

Full Text Available Fog is a factor that affects deeply the structure of vegetation of coastal deserts. Guadalupe is an oceanic island located 260 km off the coast of Baja California, and is one of the few places of the Sonoran Desert coasts with scarped coastal topography and frequent fog. With the aim to identify the effect of fog on the community of the palm forest (palmar of Brahea edulis located in the northern tip of the island: (1 we analyzed the richness and composition of vascular plants in the palmar compared to the remainder of the island, and (2 we analyzed the altitudinal variation of the abundance of palms, herbs and mosses to identify if there is altitudinal variation of the vegetation. Although species composition was not different between palmar and the rest of island, species richness and vascular plant cover were greater in the palmar. On the other hand, we found a clear altitudinal zonation of the vegetation in the palmar that is similar to that found in South American fog-driven plant communities such as the lomas. Thus, the palmar community of Guadalupe Island may be considered as a fog oasis, one of the very few that occur in North America.La niebla es un factor que afecta profundamente la estructura de la vegetación de los desiertos costeros. Guadalupe es una isla oceánica a 260 km de la costa de Baja California y constituye uno de los pocos lugares de la costa del Desierto Sonorense donde se reúnen una topografía escarpada próxima a la costa y una alta frecuencia de nieblas. Con el objeto de identificar el efecto de la niebla sobre la comunidad del palmar de Brahea edulis presente en la ladera norte de la isla: (1 analizamos la diferencia de la riqueza y la composición de plantas vasculares del palmar respecto del resto de la isla, y (2 analizamos la variación altitudinal de la abundancia de palmas, plantas acompañantes y musgo para determinar si existe variación altitudinal de la vegetación.

Full Text Available INTRODUCTION: Although the incidence of Plasmodium falciparum malaria in some parts of sub-Saharan Africa is reported to decline and other conditions, causing similar symptoms as clinical malaria are gaining in relevance, presumptive anti-malarial treatment is still common. This study traced for age-dependent signs and symptoms predictive for P. falciparum parasitaemia. METHODS: In total, 5447 visits of 3641 patients between 2-60 months of age who attended an outpatient department (OPD of a rural hospital in the Ashanti Region, Ghana, were analysed. All Children were examined by a paediatrician and a full blood count and thick smear were done. A Classification and Regression Tree (CART model was used to generate a clinical decision tree to predict malarial parasitaemia a7nd predictive values of all symptoms were calculated. RESULTS: Malarial parasitaemia was detected in children between 2-12 months and between 12-60 months of age with a prevalence of 13.8% and 30.6%, respectively. The CART-model revealed age-dependent differences in the ability of the variables to predict parasitaemia. While palmar pallor was the most important symptom in children between 2-12 months, a report of fever and an elevated body temperature of ≥37.5°C gained in relevance in children between 12-60 months. The variable palmar pallor was significantly (p<0.001 associated with lower haemoglobin levels in children of all ages. Compared to the Integrated Management of Childhood Illness (IMCI algorithm the CART-model had much lower sensitivities, but higher specificities and positive predictive values for a malarial parasitaemia. CONCLUSIONS: Use of age-derived algorithms increases the specificity of the prediction for P. falciparum parasitaemia. The predictive value of palmar pallor should be underlined in health worker training. Due to a lack of sensitivity neither the best algorithm nor palmar pallor as a single sign are eligible for decision-making and cannot replace

The aim of treating thumb fingertip amputations with no indication for replantation is to reestablish functional and esthetic properties. From March 2005 to October 2008, we treated 14 patients with thumb fingertip amputation using palmar V-Y flaps combined with bone and nail bed grafts. There were 10 men and 4 women, whose ages at surgery ranged from 19 to 63 years (mean 35.8 years). In all, 11 of the injuries occurred in the dominant hand. According to Allen's classification, two were type II, seven were type III, and five were type IV. All patients underwent emergency surgery, with a time delay after injury of 3-12 h (mean 6.4 h). In each case, the amputation was a crush or avulsion injury, making microsurgical replantation not feasible. All of the flaps survived. At 8-17 months (average 12.8 months) of follow-up, the average subjective satisfaction score was 8.64. All patients experienced cold intolerance, and none of the patients complained of dysesthesia. Favorable results (excellent or good) were found in 78.6%. Thin primary nails appeared on the grafted nail bed about 3 weeks after surgery, following which the newly formed nail thickened and developed a more natural appearance. In one case, the new nail plate showed abnormal thickening due to hyperkeratosis. The bone graft healed at 5 weeks. The mean two-point discrimination was 7.5 mm. Grip strength was 10% less than that in the unaffected hand. Metacarpophalangeal and proximal interphalangeal joint mobility losses were less than 10°. All patients returned to their jobs. No patients had postoperative complications. We believe that the combination of palmar V-Y flap and bone and nail bed grafts provides a distinct advantage over other choices. It improves function when replantation is not an option.

To investigate the feasibility and therapeutic effect of free posterior interrosseous artery flap in a bridge fashion for combined skin and bilateral artery defects at palmar side of fingers. 6 cases with combined skin and bilateral artery defects at palmar side of fingers were treated with long-pedicled free posterior interrosseous artery flap in a bridge fashion. The flap size ranged from 3.5 cm x 2.0 cm to 6.5 em x 3.0 cm. The wounds at donor sites were closed directly. All the 6 flaps survived completely without any complication, and the wounds healed primarily. The blood supply and vein drainage in all the 6 fingers were normal. 4 cases were followed up for 1-12 months (average, 7 months). Satisfactory cosmetic and functional results were achieved. The flaps looked a little bit thicker than the surrounding tissue. The long-pedicled free posterior interrosseous artery flap in a bridge fashion is a good option for reconstruction of the combined skin and bilateral artery defects at palmar side of fingers in one stage.

In 4 adult horses, simple, non displaced, incomplete fracture of the proximal extremity of the third metacarpal bone (MC3) was identified radiographically only on the dorsopalmar projection. Lameness was slight to moderate. Although nerve blocks of the foot and fetlock did not alter the lameness, high palmar regional nerve block improved the gait in 1 of the 2 horses on which it was performed. Pain on palpation or swollen distal accessory (inferior check) ligament, flexor tendons, and suspensory ligament were not found in any horse. The fracture was localized to the palmar surface of the proximal extremity of the MC3 on the basis of the intense uptake of radiopharmaceutical (99MTc-labeled sodium medronate) observed in that area during the soft tissue and delayed bone phases of a nuclear scintigraphic examination (nuclear scan) performed concurrently with radiography. Of 4 horses evaluated 6 months after the initial diagnosis, 3 had medullary sclerosis without radiographic evidence of fracture; results of follow-up nuclear scintigraphy performed in one of these horses at the same time were normal. Incomplete fracture also was suspected in another 6 adult horses with clinical lameness referable to the proximal extremity of the MC3. Although a fracture line could not be seen radiographically, trabecular hypertrophy and/or medullary sclerosis of the proximal extremity of the MC3 were detected on the dorsopalmar projection. Further, during nuclear scintigraphy, an intense uptake of the radiopharmaceutical was observed on the palmar aspect of the proximal extremity of the MC3 in all 6 horses

Due to advances in the development of the unidirectional locking plates there is now an increased use of multidirectional palmar locking plates in the treatment of distal radius factures. The purpose of this study was to evaluate a possible improvement of the treatment and results. This prospective cohort study investigated 40 patients with C1 and C2 Colles' fractures who had been treated with unidirectional and multidirectional locking plates. The average time for the follow-up examinations was 12.3 months (range 12-15 months) after surgery. The intra-operative functional (neutral-zero method), radiological and subjective (DASH score, VAS) results were evaluated. The intra-operative fluoroscopy time of the unidirectional group was 58 s shorter compared to the multidirectional group. All fractures healed without any complication. The radiological, subjective (DASH score) and objective results for both groups were good and showed no differences. Unidirectional palmar locking plates are equally suited for the therapy of C1 and C2 fractures as multidirectional palmar locking plates but multidirectional plates require a longer fluoroscopy time.

Full Text Available INTRODUÇÃO: A mobilização neural é uma técnica que visa a restauração do movimento e da elasticidade do sistema nervoso; contudo, ainda são poucos os estudos que avaliam sua eficácia sobre variáveis clínicas. OBJETIVO: Avaliar a força de preensão palmar em indivíduos submetidos à intervenção com mobilização neural. Metodologia: Estudo cruzado em que compuseram a amostra 20 sujeitos, com média de idade de 19,5 ± 0,92 anos, divididos em dois grupos (G1 e G2 que receberam, a cada semana, uma sessão única de intervenção de forma que o G1 recebeu mobilização neural e o G2 alongamentos convencionais para o supraespinal na primeira semana; o inverso aconteceu na segunda semana, em que o G1 recebeu alongamentos convencionais para o supraespinal e o G2 a mobilização neural. Os alongamentos para o supraespinal serviram apenas como placebo e não impuseram tensão aos nervos em estudo. As mobilizações neurais foram aplicadas nos nervos radial, mediano e ulnar. A força de preensão palmar foi avaliada por meio de um dinamômetro de preensão palmar em vários momentos: antes e imediatamente, 20 minutos e uma hora após cada intervenção. RESULTADOS: Não houve resultados significativos para a mobilização neural, nem para o alongamento. CONCLUSÃO: A mobilização neural não foi eficaz para produzir o aumento da força de preensão palmar em indivíduos saudáveis.

The development of multitargeted tyrosine kinase inhibitors has provided significant advances in the treatment of renal cell carcinoma. This case describes initial therapy for managing renal cell cancer with the administration of sorafenib, a multitargeted tyrosine kinase inhibitor. We report the development of localized palmar-plantar epidermal hyperplasia, a rare but significant cutaneous adverse event from sorafenib therapy. Mild-to-moderate dermatologic toxicity from sorafenib has been well described in the literature. We also review the current knowledge and the proposed hypothesis for the development of cutaneous events related to tyrosine kinase inhibitors. This particular case represents a unique form of dermatologic toxicity to sorafenib that has not previously been described in the literature.

When traumatic collateral palmar digital nerve defect occurs, emergency venous grafting is an alternative to the two-step nervous grafting procedure. During the course of a monocentric retrospective study, 12 cases of emergency venous grafting were reviewed by a single independent examiner 11 months, at least, post-intervention. Clinical and functional evaluation was carried out, together with a self-assessment of the results by the patient. Data were compacted using a filtering method and the final result was considered in terms of "good" or "bad". Good result was observed in ten cases out of 12. Bad results were associated with poor sensory recovery in the two other cases. In one of these, the bad result was also related to severe symptoms in cold conditions and a troublesome hyperesthesia. Through a review of the literature, we justify the emergency treatment of nerve defects of the collateral palmar digital nerves with venous grafting. Copyright © 2010 Elsevier Masson SAS.

To report the results of a technique of soft tissue stabilization for palmar midcarpal instability using a palmaris longus graft. In patients' symptomatic wrists with palmar midcarpal instability that had failed conservative management, we used a dorsal approach and stabilized the hamate and triquetrum by reconstructing the dorsal triquetrohamate ligament. The palmaris longus tendon graft was fixed with bone anchors. Seven wrists in 6 patients were available for follow-up at a mean of 28 months (range, 17-37 mo). There was an overall meaningful improvement in function (mean preoperative Disabilities of the Arm, Shoulder, and Hand score, 49 preoperatively, 28 postoperatively). There was a significant increase in grip strength from 15 to 21 kg. At final follow-up, 2 patients had moderate pain. The others had mild or no pain. Four patients returned to their previous occupation or activity. Patients retained full pronation and supination. When compared with the normal side, flexion was reduced to 71%, extension to 81%, radial deviation to 90%, and ulnar deviation to 65% of the opposite side. Although the mean results show an improvement, one patient had a poor result with deterioration in Disabilities of the Arm, Shoulder, and Hand score in spite of a clinically stable wrist, and another had clinical evidence of recurrent instability during pregnancy. One patient had residual symptoms from a prominent bone anchor. Overall, this technique showed good medium-term results in most of our patients. It retained some midcarpal mobility, eliminated clunking in most patients, and provided a noteworthy improvement in grip strength and function. We continue to use this technique for patients with symptomatic midcarpal instability, but it requires further evaluation with larger patient numbers and a longer follow-up to assess its overall value.

Paraneoplastic limbic encephalitis (PLE) is an autoimmune syndrome in which a non-neural tumor containing an antigen normally present in the nervous system precipitates an antibody attack on neural tissues. Patients with PLE usually present with rapidly progressive short-term memory deficits, confusion or even dementia. Palmar fasciitis and polyarthritis syndrome (PFPAS) is another autoimmune syndrome characterized by rheumatologic manifestations, especially involving the palms of the hands. We report a case of a 59-year old woman who presented with worsening neurological symptoms of two-week duration, and later coma. The combined clinical, serological, and imaging studies suggested a diagnosis of PLE. A chest computed tomographic scan showed a 1.2 cm-diameter mass in the upper lobe of the left lung that was surgically removed and showed SCLC. Following surgery, neurological symptoms rapidly improved, allowing the patient to receive adjuvant chemotherapy. While in remission for both SCLC and PLE, the patient developed pain, soft-tissue swelling, and stiffness in both palms, suggesting the diagnosis of PFPAS. Five months following the diagnosis of palmar fasciitis, SCLC relapsed with mediastinal and cervical lymphadenopathy. This case report underlines the continuous interaction of SCLC with the immune system, expressed by coexistence of two rare paraneoplastic diseases, PLE, and PFPAS, in a patient with SCLC. While symptoms related to PLE preceded the initial diagnosis of SCLC, other symptoms related to PFPAS preceded relapse.

Recent studies indicate a high prevalence of fractures of the palmar processes (PP) of the distal phalanx in foals. However, information on the prevalence of such fractures in different breeds and the effect of predisposing factors, such as hoof conformation, is limited. To examine the prevalence of distal phalanx PP fractures in foals and report the relationship of distal limb and hoof conformation with the prevalence of fracture. Longitudinal study. Front hooves of 19 Thoroughbred, Quarter Horse and Arabian foals were examined. Digital radiographic and photographic images of the distal aspect of the forelimbs were taken at ∼2.5 month intervals. Five radiographic projections of each limb were as follows: lateromedial; horizontal beam dorsopalmar; dorso60°proximal-palmarodistal oblique; dorso60°proximo45°lateral-palmarodistomedial oblique; and dorso60°proximo45°medial-palmarodistolateral oblique. The relationship between measurements and the prevalence of fractures was assessed by 3-way ANOVA. Fractures were found in 74% (n = 14) of the foals during the study period. The prevalences of lateral PP and medial PP fractures were not significantly different. Several hoof measurements were associated with PP fractures. Longer dorsal length of the distal phalanx was associated with medial PP fractures, while smaller lateral angle and shorter lateral palmar length were associated with a higher prevalence of lateral PP fractures. This study revealed a high prevalence of PP fractures in young foals, particularly in Thoroughbred foals. The hoof conformation may be one of the contributory factors to PP fractures in foals. © 2014 EVJ Ltd.

Anatomy of the palmar cutaneous branch of the median nerve: clinical significance.

1996-07-01

A detailed anatomic, histologic, and immunohistochemical study of the palmar cutaneous branch of the median nerve (PCBMN) and its distal arborization was undertaken on 12 fresh human cadaveric hands. Small unmyelinated fibers terminated in the superficial loose connective tissue of the transverse carpal ligament. There were no nerve fibers detected in the deep, dense collagen aspect of the ligament. Based on these findings, during open carpal tunnel release, the skin incision should be placed along the axis of the ring finger to avoid injury to the superficial branches of the PCBMN. When open release is used, the very small terminal branches in the loose tissue of the ligament will be transected; this may in part be responsible for postoperative soft tissue pain. For endoscopic releases, some risk for transection of the main trunk of the PCBMN at the proximal incision exists. Repeated passes of the endoscopic knife should be avoided in an attempt to limit damage to the small fibers in the superficial aspect of the ligament.

The aim of this study was to determine whether horses with a proximal palmar/plantar first phalangeal osteochondral fragment (POF) had comparable racing careers (prior to and following surgery) to horses without this fracture. A retrospective cohort study included 174 Swedish Standardbred trotters with osteochondral fragmentation in the palmar/plantar fetlock joint and 613 radiographically negative control horses presented for prepurchase examinations. Medical records and radiographs were examined for each horse. Racing data were retrieved from online Swedish Standardbred harness racing records. The effect of having a POF on race speed compared to radiographically negative control horses was examined using generalised estimating equations. Multivariable regression was used to examine differences in money earned and career longevity. The horses raced a total of 16,448 races. Horses gained speed as a function of race number. There was no difference in racing speed between horses with POF fractures that raced before surgery and control horses. Horses did not slow before, nor speed up after, surgery. There was no difference in the number of days between the last race prior to, or the first race after, the hospital visit between POF and control horses. Career earnings and lifetime starts were not significantly different between groups. The results of this study suggest the need to reevaluate the previously reported benefits of surgical intervention for POF. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available The congential anomalies involving Mullerian duct dysgenesis, the MRKH (Mayer-Rokitansky-Kuster-Hauser syndrome overlaps a ′community of syndromes′ which share, apart from a complete absence of uterus and vagina, associated presentations that include developmental abnormalities of skeletal, renal, dental and other dysmorphias. First described more than 400 years ago, this complement of anomalies now rechristened, the MRKH syndrome has been extensively studied. Found to occur once in every 4000 females; estimated on its incidence vary from 1/5000 to 1/20,000. Despite its fairly wide prevalence, this syndrome has remained largely underdiagnosed or cryptic. Social and cultural perceptions have perforce driven, the wide existence of the very personal handicap underground and unacceptable. Accidentally discovered during routine examination, during secondarily associated medical problems, the mullerian agenecies syndrome has been subject of a wide range of clinical and laboratory investigations. The oddity in the syndrome is that the patient appears absolutely normal and that it presents with no genetic marker. We herein report the palmar dermatoglyphic and doctylographic features of a patient with MRKH syndrome. However interpretation, show conclusively, at least in this single case that the MRKH syndrome can be diagnosed through its characteristic dermatography patterns. In our view, routine dermatographic study of all live females births may lead to not only an early but also a cost effective diagnostic method.

Full Text Available Background/Aim. Primary hyperhidrosis causes are unknown. The disorder begins in early childhood. It intensifies in puberty and maturity. It is equally present in both sexes. The symptoms exacerbate when the body temperature rises and due to emotional stimuli affecting the sympathetic nerve system. The aim of this study was to demonstrate that videoassisted thoracoscopic surgery (VATS sympathectomy is a method for primary focal hyperhidrosis permanent treatment. The single incision method in properly selected patients maximizes the intervention effectiveness and minimizes aesthetic side effects. Methods. This prospective study analysed the findings in patients who had been operated on due to primary focal hyperhidrosis (face, palms, and armpits using a single small transaxilarry incision in the third inter-rib space at the level of the anterior axillary line with two 5 mm flexible ports. All the patients, with T2-T5 thoracoscopic sympathectomy of the sympathetic chain using a single small incision in the third inter-rib space in the anterior axillary line, were analysed in the period from September 2009 to November 2010 regarding the postoperative morbidity and outcomes of the operation (clinical evaluation and visual analogue scale with a view to assessing the effectiveness of the surgery conducted in this manner. Results. A total of 47 patients (18 men, 29 women, 18 to 48 years old (29 on average had underwent 94 bilateral video-assisted thoracoscopic sympathectomies. The sympathectomy was indicated in cases of facial blushing and sweating (6.38%, palmary sweating (34.04%, axillary sweating (14.89% or both palmary and axillary sweating (44.68%. The largest percentage of patients (98.6% had left the hospital the following day. The postoperative 30 day’s mortality was 0 and the conversion into open surgery was not necessary.

Heo, Pilwon; Kim, Jung

2014-11-01

This paper presents a powered finger exoskeleton with an open fingerpad, named the Open Fingerpad eXoskeleton (OFX). The palmar opening at the fingerpad allows for direct contact between the user's fingerpad and objects in order to make use of the wearer's own tactile sensation for dexterous manipulation. Lateral side walls at the end of the OFX's index finger module are equipped with custom load cells for estimating the wearer's pinch grip force. A pneumatic cylinder generates assistance force, which is determined according to the estimated pinch grip force. The OFX transmits the assistance force directly to the objects without exerting pressure on the wearer's finger. The advantage of the OFX over an exoskeleton with a closed fingerpad was validated experimentally. During static and dynamic manipulation of a test object, the OFX exhibited a lower safety margin than the closed exoskeleton, indicating a higher ability to adjust the grip force within an appropriate range. Furthermore, the benefit of force assistance in reducing the muscular burden was observed in terms of muscle fatigue during a static pinch grip. The median frequency (MDF) of the surface electromyography (sEMG) signal from the first dorsal interosseous (FDI) muscle displayed a lower reduction rate for the assisted condition, indicating a lower accumulation rate of muscle fatigue.

Chronic arsenic exposure can lead to palmoplantar keratosis. In the stratum corneum of skin, linoleic acid is of the utmost importance to the inflammation, keratinization, and regeneration processes. The aims of this study were: (i) to present quantitative information on the linoleic acid fraction of intercorneocyte lipids, and (ii) to elucidate the role of linoleic acid in the pathophysiology of arsenical keratosis. Lipid extracts were collected from keratotic lesions in seven patients, seven arsenic-exposed subjects, and seven non-exposed control subjects. Linoleic acid levels of the specimens were estimated by reverse-phase high-performance liquid chromatography (RP-HPLC). There was a significant (P keratosis patients (palm: 25.66 ± 4.95 μg/cm(2); dorsum: 28.25 ± 6.20 μg/cm(2)) compared with arsenic-exposed (palm: 2.75 ± 0.85 μg/cm(2); dorsum: 1.96 ± 0.64 μg/cm(2)) and non-exposed (palm: 1.52 ± 0.61 μg/cm(2); dorsum: 1.28 ± 0.39 μg/cm(2)) control subjects. There was no significant difference (P = 0.556) in linoleic acid concentration in the non-affected skin of the dorsum of the hand (28.25 ± 6.20 μg/cm(2)) compared with that in the palmar sites (25.66 ± 4.95 μg/cm(2)) in the patient group. The change in linoleic acid levels in the arsenic-exposed control group did not differ from that in non-exposed controls (P = 1.000). Linoleic acid concentration is elevated in arsenical keratosis; this finding warrants further investigation to ascertain whether linoleic acid plays a direct role in the pathophysiology of arsenical keratosis. © 2015 The International Society of Dermatology.

To estimate cost-effectiveness of botulinum toxin therapy for axillary hyperhidrosis compared to the standard surgical intervention of endoscopic thoracic sympathectomy (ETS). The validated dermatology life quality index questionnaire was given to patients attending for treatment over a 4 month period, to assess their quality of life (QoL) over the preceding week (n = 44). Follow-up was performed 4-6 weeks later by telephone using the same questionnaire to validate the effectiveness of the treatment. The duration of effect of the botulinum toxin treatment was also recorded and this data was used as the basis for cost effectiveness analysis. Using HIPE data, the baseline cost for single intervention using botulinum toxin and ETS was retrieved. Using figures provided by HIPE and expert opinion of the costs of complications, a stochastic model for 10,000 patients was used to evaluate the total costs for ETS including the complications. The results from the QoL analysis show that botulinum toxin therapy is a successful therapy for improvement of symptoms. It was revealed that the mean interval before recurrence of original symptoms after botulinum toxin therapy was 5.6 months. The baseline cost for both treatments are €389 for botulinum toxin and €9389 for uncomplicated ETS. The stochastic model yields a mean cost of €11,390 for ETS including complications. Treatments reached cost equivalence after 13.3 years. However, given the efficacy of the botulinum toxin therapy and the low risk we propose that botulinum toxin therapy for hyperhidrosis should be considered the gold standard.

2017-11-01

The main aim of the present paper is to describe the first Detarioideae fossil woods from El Palmar Formation (Late Pleistocene) in the Uruguay River Basin (Entre Ríos, Argentina). This study is based on five silicified wood specimens preserved in fluvial deposits, which were transported from their growth site. Two new genera and species are described: Paraoxystigma concordiensis gen. nov and sp. nov. has medium-sized vessels, paratracheal axial parenchyma, heterocellular and multiseriate rays, and diffuse axial canals similar in size and shape to vessels, and Gossweilerodendroxylon palmariensis gen. nov and sp. nov. has medium-sized vessels, alternate intervessel pits, paratracheal and apotracheal axial parenchyma, homocellular and uni to-multiseriate rays, and small diffuse axial canals. These Detarioideae fossil records in south-eastern South America support the existence of a very old relationship with the extant West African forests. Eco-anatomical features observed in these fossil woods, along with the climatic information available from the Nearest Living Relatives (NLRs) comparison, suggest warm and humid climatic conditions for the upper-middle basin of the Uruguay River during some periods of the Late Pleistocene.

Full Text Available Childhood Anemia is a major public health problem in Indonesia. Because of lack of laboratory facilities, most of primary health facilities have to rely on physical signs and not laboratory tests to detect anaemic patients who need therapy. The objective of this study was to assess the validity of palmar pallor as diagnosis of anaemia. This study identified anaemia in primary health center by two physicians and two health workers. The samples were children with illnes (6 months < 60 months who came to primary health center. Each sample was examined by two physicians and two health workers by measuring Hemoglobine concentration using by Cyantmeth method. A total of 123 samples were examined: 65 males (52.8%, 58 females (47.2%, The mean of age was 26 months, whereby the youngest was 6 months and the oldest was 59 months.

Full Text Available Temperature is an important and common variable that modifies nerve conduction study parameters in practice. Here we compare the effect of cooling on the mixed palmar median to ulnar negative peak-latency difference (PMU in electrodiagnosis of carpal tunnel syndrome (CTS. Controls were 22 subjects (19 women, mean age 42.1 years, 44 hands. Patients were diagnosed with mild symptomatic CTS (25 women, mean age 46.6 years, 34 hands. PMU was obtained at the usual temperature, >32°C, and after wrist/hand cooling to Temperatura é uma variável comum e importante que modifica os parâmetros de condução nervosa na prática eletrodiagnóstica. Neste trabalho nós estudamos o efeito do esfriamento na diferença de latências palmares entre o nervo mediano e ulnar (PMU, segmento palma-pulso, utilizada rotineiramente para o eletrodiagnóstico da síndrome do túnel do carpo (STC. Foram estudados 22 controles (19 mulheres, média de idade 42,1 anos, 44 mãos e 25 pacientes (25 mulheres, média de idade 46,6 anos, 34 mãos com diagnóstico de STC leve. PMU foi obtida em temperatura usual (>32°C, e após resfriamento de mão/pulso em água com gelo (<27°C. Após o resfriamento houve aumento significativo na PMU e na latência mista palmar do nervo ulnar nos pacientes quando comparados aos controles. Nós concluímos que o resfriamento modifica significativamente a PMU e propomos que as latências obtidas em nervos submetidos à compressão reagem de maneira mais acentuada ao frio e isso poderia ser uma arma útil para o eletrodiagnóstico da STC incipiente. Da mesma forma, houve reação mais acentuada ao frio no estudo da latência mista palmar do nervo ulnar nos pacientes mas não nos controles, que poderia levantar a hipótese de compressão subclínica do nervo ulnar.

Hand eczema is a common inflammatory dermatosis that causes significant patient morbidity. Previous studies comparing psoralen-ultraviolet A (PUVA) with narrowband ultraviolet B (NB-UVB) have been small, nonrandomized and retrospective. To conduct an observer-blinded randomized controlled pilot study using validated scoring criteria to compare immersion PUVA with NB-UVB for the treatment of chronic hand eczema unresponsive to topical steroids. Sixty patients with hand eczema unresponsive to clobetasol propionate 0·05% were randomized to receive either immersion PUVA or NB-UVB twice weekly for 12 weeks with assessments at intervals of 4 weeks. The primary outcome measure was the proportion of patients achieving 'clear' or 'almost clear' Physician's Global Assessment (PGA) response at 12 weeks. Secondary outcome measures included assessment of the modified Total Lesion and Symptom Score (mTLSS) and the Dermatology Life Quality index (DLQI). In both treatment arms, 23 patients completed the 12-week assessment for the primary outcome measure. In the PUVA group, five patients achieved 'clear' and eight 'almost clear' [intention-to-treat (ITT) response rate 43%]. In the NB-UVB group, two achieved 'clear' and five 'almost clear' (ITT response rate 23%). For the secondary outcomes, median mTLSS scores were similar between groups at baseline (PUVA 9·5, NB-UVB 9) and at 12 weeks (PUVA 3, NB-UVB 4). Changes in DLQI were similar, with improvements in both groups. In this randomized pilot trial recruitment was challenging. After randomization, there were acceptable levels of compliance and safety in each treatment schedule, but lower levels of retention. Using validated scoring systems - PGA, mTLSS and DLQI - as measures of treatment response, the trial demonstrated that both PUVA and NB-UVB reduced the severity of chronic palmar hand eczema. © 2017 British Association of Dermatologists.

Child palm burns arise by contact and are often deep. The singular difficulty of such a disease comes from the necessity of the child growth and from the potential occurrence of constricted scars. In order to avoid sequelae, the actual gold standard is to practice an early excision of the burn, followed by a skin graft. The aim of this study is to evaluate the results of spontaneous healing combined with rehabilitation versus early skin grafting and rehabilitation concerning the apparition of sequelae. We performed a retrospective study in two burn centers and one rehabilitation hospital between 1995 and 2010. Eighty-seven hands have been included in two groups: one group for spontaneous healing and the other group for excision and skin grafting. Every child benefited from a specific rehabilitation protocol. The two main evaluation criteria were the duration of permanent splint wearing and the number of reconstructive surgery for each child. The median follow-up duration is about four years. The two groups were comparable. For the early skin grafting group, the splint wearing duration was 1/3 longer than for the spontaneous healing group. Concerning the reconstructive surgery, half of the grafted hands needed at least one procedure versus 1/5 of spontaneous healing hands. Our results show the interest of spontaneous healing in palmar burn in child, this observation requires a specific and intense rehabilitation protocol. Copyright © 2016 Elsevier Masson SAS.

Treatment of type III middle phalangeal neck fractures through a palmar approach: a case report

Full Text Available 【Abstract】 Phalangeal neck fractures occur almost exclusively in children. We present the case of a 49 years old man with a dislocated fracture of the neck of the middle phalanx with the distal fragment rotated at 180°, due to a traumatic circular saw injury to the left index, which was solved by anatomical reduction and bone fixation with two 1.5 mm Synthes screws and a temporary transarticular K-wire at the distal interphalangeal joint. Zone I flexor digitorum profundus repair was performed using a modification of the Kessler 4-strands core suture and a full-thickness skin graft from the hypothenar eminence was taken to cover the skin gap. At 6-month follow-up the patient was pain-free and with a total active movement equivalent to 190°. No radio-logical signs of avascular necrosis of the head of the middle phalanx or nonunion of the distal fragment was detectable with recovery to the previous manual work. Owing to the position of the phalangeal head maintained in position by the collateral ligaments an anatomic reduction from dorsal approach is difficult to be performed and a longitudinal trac-tion can render the reduction harder too. The volar approach permits an easier reduction of the fracture through a derotation of the distal fragment facing palmar. Key words: Finger phalanges; Fractures, bone; Finger joint

Fibrocartilage degeneration is the earliest pathologic finding in navicular disease but remains difficult to detect, even with magnetic resonance (MR) imaging. We hypothesized that injection of the navicular bursa with saline would improve accuracy of MR imaging evaluation of palmar fibrocartilage. Thoracic limbs were collected from 11 horses within 6 h of death. Imaging was performed with a 1.5 T magnet using sagittal 2D proton density and transverse 3D FLASH sequences with fat saturation. For the purpose of determining sensitivity and specificity of the MR images, fibrocartilage was classified as normal or abnormal, based on combination of the findings of gross and microscopic pathology. Thickness of fibrocartilage was measured on histologic sections and corresponding transverse FLASH MR images before and after injection of saline. A paired Student's t-test was used for comparison of measurements. Partial thickness fibrocartilage loss was present in 6 of 22 limbs. Sensitivity of precontrast MR images for detection of lesions was 100% while specificity was 6%. Saline MR arthrography resulted in both sensitivity and specificity of 100% based on consensus review. Mean histologic fibrocartilage thickness was 0.75 +/- 0.12 mm. Mean fibrocartilage thickness on precontrast transverse FLASH images was 0.93 +/- 0.065 and 0.73 +/- 0.09 mm on postsaline images. The histologic cartilage thickness was signficantly different from that in precontrast images (Pfibrocartilage can only be evaluated reliably for the presence of partial thickness lesions after intrabursal injection of saline.

To describe the magnetic resonance (MR) imaging and gross anatomic appearance of the scaphocapitate (SC) ligament and triquetrohamocapitate (THC) ligament, which are the radial and ulnar limbs of the composite arcuate ligament, a critical volar midcarpal stabilizing ligament. T1 spin-echo and 3D gradient-echo MR imaging in the standard, coronal oblique, and axial oblique planes were performed both before and following midcarpal arthrography in seven cadaveric wrists. The seven specimens were then sectioned in selected planes to optimally visualize the SC and THC ligaments. These specimens were analyzed and correlated with their corresponding MR images. The SC and THC ligaments can be visualized in MR images as structures of low signal intensity that form an inverted ''V'' joining the proximal and distal carpal rows. The entire ligamentous complex is best visualized with coronal and axial oblique MR imaging but can also be seen in standard imaging planes. SC and THC ligaments together form the arcuate ligament of the wrist. Their function is crucial to the normal functioning of the wrist. Palmar midcarpal instability (PMCI) is a resulting condition when abnormalities of these ligaments occur. Dedicated MR imaging in the coronal and axial imaging planes can be performed in patients suspected of having PCMI. (orig.)

Full Text Available El Parque Nacional El Palmar, Entre Ríos, preserva desde 1965 el mayor remanente de la sabana de Butia yatay , un ecosistema rico en especies amenazado por la actividad humana. Para estudiar el funcio - namiento de este ecosistema y gestionar su preservación, es necesario contar con una adecuada carac - terización de la heterogeneidad de su vegetación. En este trabajo presentamos una clasificación fitoso - ciológica de las comunidades vegetales de la sabana del Parque, describimos su estructura, composición y diversidad florística y detallamos su distribución en el paisaje. Con el fin de estratificar la obtención de datos, delimitamos primero las principales unidades geomorfológicas del paisaje. En la primavera de 1999 y en el verano siguiente, realizamos censos florísticos completos en 73 “stands” de sabana con diferentes historias de incendio, distribuidos en las diferentes unidades geomorfológicas. Utilizamos técnicas de análisis multivariado y clasificación numérica para agrupar los censos en comunidades y las especies en grupos florísticos. Finalmente, resumimos las diferencias entre las comunidades en un esca - lamiento multidimensional métrico. Obtuvimos 7 comunidades, descriptas por 20 grupos florísticos. El patrón de similitudes entre estas comunidades sugiere que la heterogeneidad florística se ordena según dos componentes, uno asociado con diferencias en la textura del suelo y el otro con diferencias en el régimen de humedad del suelo. Tres de las comunidades, afines entre sí, se distribuyen en las terrazas altas e interfluvios que conforman la matriz del paisaje, en correspondencia con diferencias graduales de topografía y suelos. Estas comunidades cambian sucesionalmente por el avance de la lignificación des - encadenada por la exclusión del ganado y mantenida por la escasez de incendios naturales. Las restantes cuatro comunidades aparecen estrictamente asociadas con afloramientos rocosos, dep

This review of the literature on palmoplantar hypokeratosis, a process that was first indentified only 10 years ago, discusses the current state of our understanding, the therapeutic options available, and the debate about etiology. Forty-four publications reporting 69 cases were found. Palmar or plantar hypokeratosis occurs mainly in women (76.8%) and age at the time of a first visit to a physician ranges from 42 to 84 years. Most cases present between the ages of 51 and 70 years. The majority of patients have had solitary lesions usually located on the right palm, particularly in the regions of the thenar (in 44/79 lesions [55.7%]) or hypothenar eminences (in 11/79 lesions [13.9%]). In only 8 cases was there a history of prior trauma at the site. Studies using polymerase chain reaction techniques to identify human papillomavirus involvement were negative in most cases. These hypokeratotic lesions are localized epidermal depressions formed by an abrupt thinning of the stratum corneum, providing a singular histopathologic feature. This condition can currently be considered a localized keratinization disorder affecting zones where there is a thick stratum corneum. The precipitating cause is unknown and a definitive treatment remains to be found. The mechanism would be the localized failure of a clone of keratinocytes during differentiation toward normal palmoplantar hyperkeratinization. Copyright © 2012 Elsevier España, S.L. y AEDV.

Most atlases and textbooks dealing with human anatomy do not refer to the "pollical palmar interosseous" (PPI) muscle of Henle. In order to undertake a fresh and detailed study of this muscle and to thus better understand human comparative anatomy and evolution, we: 1) analyze the frequency of the PPI in a large sample of human hands; 2) describe the attachments, innervation and varieties of the PPI in these hands; 3) compare the data obtained with the information available in the literature; and 4) discuss the phylogenetic origin of the PPI and the implications of our observations and comparisons for medicine and for the understanding of human evolutionary history. Within the 72 hands dissected by us, the PPI is present in 67 hands (93%), commonly having a single muscular branch, originating from the medial side of the base of metacarpal I only, inserting onto the medial side of the base of the pollical proximal phalanx and/or surrounding structures (e.g., ulnar sesamoid bone, wing tendon of extensor apparatus), and passing at least partially, and usually mainly, medial to the princeps pollicis artery. A careful study of the human PPI, as well as a detailed comparison with other mammals, strongly suggest that the muscle is evolutionarily derived from the adductor pollicis, and namely from its oblique head. Therefore, we propose that PPI should be designated by the name musculus adductor pollicis accessorius, which indicates that the muscle is most likely a de novo structure derived from the adductor pollicis.

In this study, angiography of normal digits of camel has been accomplished, and the vessels of digits and its distribution have been evaluated to be compared with abnormal digits in the future studies. The thoracic and pelvic limb of 16 camels were collected immediately following slaughter. The palmar and plantar arteries were isolated and catheterised by 18-gauge angiocatheter needle; perfused by 40Ð’–50 ml of iodinated compound injected into each vessel. Angiograms were obtained using dorsopalmer, dorsoplanter and latero-medial projections. In the pelvic limb, above the fetlock joint, the deep palmar arch communicates with the median artery via the anastomotic branch, forming the superfcial palmar arch, from which two branches were clear, 1-palmar common digital artery IV that divides into palmar proper digital arteries IV and V, close to the lateral accessory (ffth) digit. 2-Palmar common digital artery III, produces the first branch and continues distally near the middle of the proximal phalanx, it gives off two palmar branches of the proximal phalanx. Vascular distribution of the pelvic limb was similar to thoracic limb, carrying the name of plantar instead of palmar

In the autonomic nerve system most sympathetic neurons synapse peripherally in the ganglia of the sympathetic trunk. A reduction in sympathicotonia by partial elimination of these ganglia is a therapeutic approach that has been used for more than 100 years. In the early 1920s the first attempts at percutaneous sympathicolysis (SL) were carried out. Nowadays, minimally invasive image-guided SL has become an integral part of interventional radiology. Established indications for SL are hyperhidrosis, critical limb ischemia and the complex regional pain syndrome. The standard imaging guidance modality in SL is computed tomography (CT) which allows the exact placement of the puncture needle in the target area under visualization of the surrounding structures. Ethanol is normally used for chemical lysis, which predominantly eliminates the unmyelinated autonomic axons. In order to visualize the distribution of the ethanol during application, iodine-containing contrast medium is added. The sympathetic nervous system (SNS) controls sweat secretion via the efferent neurons; therefore, effective therapy of idiopathic palmar, axillary and plantar hyperhidrosis can be achieved when SL is performed at the corresponding level of the sympathetic trunk. Furthermore, due to the vasomotor innervation of most blood vessels, by reduction of the sympathicotonus an atony of the smooth muscles and therefore vasodilatation occurs, which is used as a palliative therapeutic option in patients with critical limb ischemia. By elimination of the afferent sensory fibers this also results in pain relief. This principle is also used in the SL therapy of the complex regional pain syndrome. After the introduction of CT guidance, major complications have become rare events. In addition to the usual risks of percutaneous interventions there are, however, a number of specific complications, such as syncope caused by irritation of cardiac sympathetic nerves in thoracic SL and ureteral injury in lumbar

Full Text Available Background: In present study, we tried to determine significant palmar dermatoglyphic parameters in case of essential hypertensive’s in age group between 20-50 years and whether the parameters can be used for screening purpose i.e., early detection of hypertension. Method: With the use of modified Purvis Smith method, Black duplicating ink (Kores, Bombay was smeared on both hands one by one and prints will be taken by rolling the hands from wrist creases to finger tips on the roller covered with bond paper. While crystal bond paper, applied firmly over a wooden pad, was used for recording the inked epidermal ridge patterns. Rolled finger prints were recorded after applying uniform pressure on white bond paper from ulnar to radial side. Complete palm impression, including the hollow or the palm was obtained over paper. Thus one set of finger prints and palm prints was obtained. The prints obtained were immediately examined with hand-lens. Result: Right hand and left hand of the both male and female study group showed more number of arches than controls. Right hand and left hand of the both male and female study group showed more number of Radial loops than controls. The right hand and left hand of both male and female control group showed more number of ulnar loops than study group. The right hand and left hand of the male control group showed more number of Whorls than study, while in females, the right hand study group showed more number of whorls than control group and the left hand study group showed less number of Whorls as compared to control group. Conclusion: The present study indicates that there are some genetic factors which are involved in the causation of essential hypertension and it is possible to certain extent to predict from dermatoglyphics individual’s chance of acquiring essential hypertension. Like clinical history, examination and investigations, the dermatoglyphics will play an important role revealing the genetic

Proximal palmar/plantar osteochondral fragmentation of the first phalanx is a frequent radiographic finding in Standardbred horses. These lesions are routinely removed prior to the onset of a racing career with no evidence to support the timing of this surgical intervention. To determine whether horses racing before surgery slowed as they approached surgery date and whether they speeded up after surgery. To investigate the factors affecting whether a horse raced after surgery and compare the performance of horses that did and did not race before surgery. A retrospective study using 193 Swedish Standardbred trotters. Medical records and radiographs of each horse were examined. Racing data were retrieved from official online records. Generalising estimating equations were used to examine presurgery racing performance and determine whether this differed between horses that raced before surgery and those that had not. Multivariable regression was used to examine career earnings and number of career races. Horses racing before surgery neither slowed as they approached surgery, nor speeded up after surgery. Race speed of horses raced before surgery was not different from those that only raced after surgery. Racing before surgery was not associated with whether horses raced following surgery. Only horses with 3 affected legs had slower race speeds than other horses. No other horse level variables affected race speed, number of career races, career earnings or top speed. There was no significant difference in race speed between horses that raced before surgery and those that did not. Horses did not slow down prior to surgery. Horses with 3 affected legs ran slower than those with only a single or 2 affected limbs. There was no association between timing of surgery and race speed or career longevity. The potential benefits of surgical intervention should be critically examined. © 2014 EVJ Ltd.

Full Text Available La enfermedad de Charcot-Marie-Tooth constituye elgrupo de neuropatías periféricas hereditarias más común a nivel mundial. Una familia con 18 afectados del cantón de Palmares (Alajuela, Costa Rica con una neuropatía de tipo axonal y herencia autosómica recesiva, permitió localizar el gen responsable en la región 19q13.33. Posteriormente se identificó la mutación causante en el gen MED25. El presente estudio determinó la frecuencia del alelo mutante, así como la distribución geográfica de este alelo. En una muestra al azar de 103 individuos se encontraron seis individuos heteroigotas para la mutación, distribuidos por todo el cantón. No se encontró ninguna persona en estado homocigota para este alelo. No hallamos algunacaracterística clínica que difiera significativamente entre los individuos homocigotos silvestres y los heterocigotos para la mutación. El 5.83% de la población es heterocigota y la frecuencia del alelo Ala335Val es de 0.029, seis veces mayor que en una muestra de toda la población costarricense. Por esta razón se recomienda un análisis molecular de portadores con el fin de alertar sobre la posibilidad de aparición de más casos en el cantón.

Biofeedback can improve cutaneous problems that have an autonomic nervous system component. Examples include biofeedback of galvanic skin resistance (GSR) for hyperhidrosis and biofeedback of skin temperature for Raynaud's disease. Hypnosis may enhance the effects obtained by biofeedback. Cognitive-behavioral methods may resolve dysfunctional thought patterns (cognitive) or actions (behavioral) that damage the skin or interfere with dermatologic therapy. Responsive diseases include acne excoriée, atopic dermatitis, factitious cheilitis, hyperhidrosis, lichen simplex chronicus, needle phobia, neurodermatitis, onychotillomania, prurigo nodularis, trichotillomania, and urticaria. Hypnosis can facilitate aversive therapy and enhance desensitization and other cognitive-behavioral methods. Hypnosis may improve or resolve numerous dermatoses. Examples include acne excoriée, alopecia areata, atopic dermatitis, congenital ichthyosiform erythroderma, dyshidrotic dermatitis, erythromelalgia, furuncles, glossodynia, herpes simplex, hyperhidrosis, ichthyosis vulgaris, lichen planus, neurodermatitis, nummular dermatitis, postherpetic neuralgia, pruritus, psoriasis, rosacea, trichotillomania, urticaria, verruca vulgaris, and vitiligo. Hypnosis can also reduce the anxiety and pain associated with dermatologic procedures.

We retrospectively evaluated the safety and efficacy of computed tomography-guided placement of percutaneous catheters in close proximity to the thoracic sympathetic chain by rating pain intensity and systematically reviewing charts and computed tomography scans. Interventions were performed 322 times in 293 patients of mean (SD) age 59.4 (17.0) years, and male to female ratio 105:188, with postherpetic neuralgia (n = 103, 35.1%), various neuralgias (n = 88, 30.0%), complex regional pain syndrome (n = 69, 23.6%), facial pain (n = 17, 5.8%), ischaemic limb pain (n = 7, 2.4%), phantom limb pain (n = 4, 1.4%), pain following cerebrovascular accident (n = 2, 0.7%), syringomyelia (n = 2, 0.7%) and palmar hyperhidrosis (n = 1, 0.3%). The interventions were associated with a total of 23 adverse events (7.1% of all procedures): catheter dislocation (n = 9, 2.8%); increase in pain intensity (n = 8, 2.5%); pneumothorax (n = 3, 0.9%); local infection (n = 2, 0.6%); and puncture of the spinal cord (n = 1, 0.3%). Continuous infusion of 10 ml.h(-1) ropivacaine 0.2% through the catheters decreased median (IQR [range]) pain scores from 8 (6-9 [2-10]) to 2 (1-3 [0-10]) (p < 0.0001). Chemical neuroablation was necessary in 137 patients (46.8%). We conclude that this procedure leads to a significant reduction of pain intensity in otherwise obstinate burning or stabbing pain and is associated with few hazards. © 2011 The Authors.

2011-01-01

Measurements of blood volume pulse (BVP) and skin conductance are commonly used as indications of psychological arousal in affective computing and human–machine interfaces. To date, palmar surfaces remain the primary site for these measurements. Placement of sensors on palmar surfaces, however, is undesirable when recordings are fraught with motion and pressure artifacts. These artifacts are frequent when the human participant has involuntary movements as in hyperkinetic cerebral palsy. This motivates the use of alternative measurement sites. The present study examined the correlation between measurements of blood volume pulse and skin conductance obtained from three different sites on the body (fingers, toes and ear for BVP; fingers, toes and arch of the foot for skin conductance) in response to cognitive and affective stimuli. The results of this pilot study indicated significant inter-site correlation among signal features derived from different sites, with the exception of BVP amplitude, the number of electrodermal reactions and the slope of the electrodermal activity response. We attribute these differences in part to inter-site discrepancies in local skin conditions, such as skin temperature. Despite these differences, significant changes from baseline were present in the responses to the cognitive and affective stimuli at non-palmar sites, suggesting that these sites may provide viable signal measurements for use in affective computing and human–machine interface applications

Full Text Available The clinical and histopathological effects of two alcoholic neurolytics were studied in horses. Normal horses were shod with a designed shoe adaptted with 5 screws to produce solar pain. After gait and lameness score analysis, the palmar nerve of 5 horses was injected with 5 ml of 0,75% benzyl alcohol (Group A and 5 horses were injected with 5 ml of absolute ethyl alcohol (Group B. The animals were submitted to regular lameness evaluation and solar sensibility tests during next six months. The solar sensitivity returned 5 months latter in the group injected with benzyl alcohol 0,75%, while in the group injected with absolute ethyl alcohol, the sole was still desensitized 6 months latter. The histopathological findings showed that the nerve injected with benzyl alcohol 0,75%, resulted in axonotmesis, characterized by axonal nerve degeneration, with possibilities for the nerve conduction recovery. The perineural injection of ethyl alcohol absolute, resulted in neurotmesis with difficult nerve regeneration. It was concluded that chemical neurolysis with alcohol is an option for temporary or permanent nerve blocks in horses.

Com o objetivo de avaliar os resultados em longo prazo, os pacientes foram convocados. Houve o retorno de 44 pacientes. Deste total, três pacientes, por terem doenças associadas, foram excluídos, resultando, um total de 53 mãos analisadas. Apresentaremos os resultados da avaliação subjetiva, obtidos através da aplicação de um teste de auto-avaliação chamado de questionário de Boston. Este questionário consiste em perguntas que avaliam a gravidade dos sintomas e o estado funcional no momento da aplicação do mesmo. Através da aplicação do referido questionário encontramos um escore de 1,41 ± 0,57 para gravidade dos sintomas e 1,59 ± 0,93 para o estado funcional. Como este questionário não foi aplicado no pré-operatório deste grupo de pacientes analisados, comparou-se a pontuação obtida com as encontradas na literatura pertinente. Os resultados obtidos demonstraram que as pontuações pós-operatórias são similares àquelas existentes na literatura, mesmo sendo referidas a tempos diferentes de seguimento pós-operatórios, concluindo que havendo uma melhora dos sintomas, o questionário de Boston é sensível a esta mudança clínica.Between the years of 1995 and 1998, 112 surgeries were performed for treating Carpal Tunnel Syndrome (CTS using the technique of palmar incision employing the Paine retinaculum.

2017-01-01

Introduction: The aim of the present study is to develop a heuristic that could replace the surgeon's analysis for the decision on the operative approach of distal radius fractures based on simple fracture characteristics. Patients and methods: Five hundred distal radius fractures operated between 2011 and 2014 were analyzed for the surgeon's decision on the approach used. The 500 distal radius fractures were treated with open reduction and internal fixation through palmar, dorsal, and dorsopalmar approaches with 2.4 mm locking plates or underwent percutaneous fixation. The parameters that should replace the surgeon's analysis were the fractured palmar cortex, and the frontal and the sagittal split of the articular surface of the distal radius. Results: The palmar approach was used for 422 (84.4%) fractures, the dorsal approach for 39 (7.8%), and the combined dorsopalmar approach for 30 (6.0%). Nine (1.8%) fractures were treated percutaneously. The correlation between the fractured palmar cortex and the used palmar approach was moderate (r=0.464; p<0.0001). The correlation between the frontal split and the dorsal approach, including the dorsopalmar approach, was strong (r=0.715; p<0.0001). The sagittal split had only a weak correlation for the dorsal and dorsopalmar approach (r=0.300; p<0.0001). Discussion: The study shows that the surgical decision on the preferred approach is dictated through two simple factors, even in the case of complex fractures. Conclusion: When the palmar cortex is displaced in distal radius fractures, a palmar approach should be used. When there is a displaced frontal split of the articular surface, a dorsal approach should be used. When both are present, a dorsopalmar approach should be used. These two simple parameters could replace the surgeon's analysis for the surgical approach.

Full Text Available Psoriasis is a chronic inflammatory condition with variable changes on the skin and nails, sometimes associated with osteoarticular manifestations characterizing the psoriatic arthritis. This arthritis may precede, follow, or be concomitant with the skin lesions of psoriasis. Unsuspected psoriatic arthritis may be misdiagnosed by other seronegative spondyloarthritis, mainly in primary care attention, and ominous outcomes are related to late and inadequate management. Therefore, diagnostic exercises with base on significant clinical and radiological images might contribute to enhance the suspicion index about these challenging conditions.

The authors reviewed the outpatient charts diagnosed as hyperthyroidism at Srinagarind Hospital from June 1998-June 2004. The objective was to compare the clinical features of hyperthyroidism in patients older and younger than 60 years old. There were 922 cases enrolled, 84 cases (9.11%) were 60 years old and above. The female: male ratio was 3.4:1 and 4:1 and the mean ages were 64.2 +/- 3.7 and 37.4 +/- 11.2 years old in the elder and younger group, respectively. The common presentations were dyspnea (94.1, 96.5%), weight loss (93.8, 87.9%) and palpitation (83.3, 93.1%) in the elder and younger, respectively. The more significant clinical presentations in the elder group were atrial fibrillation, weakness and anorexia whereas exophthalmos, goiter, heat intolerance and hyperhidrosis were not as frequent. Thus, the classic presentations often lacked in the elder group. Therefore, unexplained AF, weakness and anorexia should not exclude hyperthyroidism even with paucity of typical clinical features.

Variations in the nerves of the thumb and index finger.

The digital nerves to the thumb and index finger have been studied by dissecting twenty-five embalmed upper limbs. The palmar digital nerves to the thumb were constant in position and course, with a short lateral cutaneous branch from the radial palmar digital nerve in 30 per cent of cases. The palmar digital nerves to the index finger had a variable pattern, the commonest arrangement, well described in Gray's Anatomy, occurring in 74 per cent of cases. The variations and their frequency are described. By examining histological cross-sections of the index finger it was found that of about 5,000 endoneurial tubes entering the finger, 60 per cent passed beyond the distal digital crease to supply the pulp and nail bed. The depth of the palmar digital nerves was about 3 millimetres, but less at the digital creases, and their diameter lay between 1 and 1.5 millimetres as far as the distal digital crease. Clinical applications of the findings are discussed.

CT-guided percutaneous neurolysis methods. State of the art and first results

Schneider, B.; Richter, G.M.; Roeren, T.; Kauffmann, G.W.

1996-01-01

We used 21G or 22G fine needles. All CT-guided percutaneous neurolysis methods require a proper blood coagulation. Most common CT scanners are suitable for neurolysis if there is enough room for maintaining sterile conditions. All neurolysis methods involve sterile puncture of the ganglia under local anesthesia, a test block with anesthetic and contrast agent to assess the clinical effect and the definitive block with a mixture of 96% ethanol and local anesthetic. This allows us to correct the position of the needle if we see improper distribution of the test block or unwanted side effects. Though inflammatory complications of the peritoneum due to puncture are rarely seen, we prefer the dorsal approach whenever possible. Results: Seven of 20 legs showed at least transient clinical improvement after CT-guided lumbar sympathectomies; 13 legs had to be amputated. Results of the methods in the literature differ. For lumbar sympathectomy, improved perfusion is reported in 39-89%, depending on the pre-selection of the patient group. Discussion: It was recently proved that sympathectomy not only improves perfusion of the skin but also of the muscle. The hypothesis of a steal effect after sympathectomy towards skin perfusion was disproved. Modern aggressive surgical and interventional treatment often leaves patients to sympathectomy whose reservers of collateralization are nearly exhausted. We presume this is the reason for the different results we found in our patient group. For thoracic sympathectomy the clinical treatment depends very much on the indications. Whereas palmar hyperhidrosis offers nearly 100% success, only 60-70% of patients with disturbance of perfusion have benefited. Results in celiac ganglia block also differ. Patients with carcinoma of the pancreas and other organs of the upper abdomen benefit in 80-100% of all cases, patients with chronic pancreatitis in 60-80%. (orig./VHE) [de

Transcranial focused ultrasound (FUS) is gaining momentum as a novel non-invasive brain stimulation method, with promising potential for superior spatial resolution and depth penetration compared to transcranial magnetic stimulation or transcranial direct current stimulation. We examined the presence of tactile sensations elicited by FUS stimulation of two separate brain regions in humans-the primary (SI) and secondary (SII) somatosensory areas of the hand, as guided by individual-specific functional magnetic resonance imaging data. Under image-guidance, acoustic stimulations were delivered to the SI and SII areas either separately or simultaneously. The SII areas were divided into sub-regions that are activated by four types of external tactile sensations to the palmar side of the right hand-vibrotactile, pressure, warmth, and coolness. Across the stimulation conditions (SI only, SII only, SI and SII simultaneously), participants reported various types of tactile sensations that arose from the hand contralateral to the stimulation, such as the palm/back of the hand or as single/neighboring fingers. The type of tactile sensations did not match the sensations that are associated with specific sub-regions in the SII. The neuro-stimulatory effects of FUS were transient and reversible, and the procedure did not cause any adverse changes or discomforts in the subject's mental/physical status. The use of multiple FUS transducers allowed for simultaneous stimulation of the SI/SII in the same hemisphere and elicited various tactile sensations in the absence of any external sensory stimuli. Stimulation of the SII area alone could also induce perception of tactile sensations. The ability to stimulate multiple brain areas in a spatially restricted fashion can be used to study causal relationships between regional brain activities and their cognitive/behavioral outcomes.

2016-01-01

The management of distal radial fractures is guided by the interpretation of radiographic findings. The aim of this investigation was to determine the intra- and inter-observer reliability of eight traditionally reported anatomic radiographic parameters in adults with an acute distal radius fracture. Five observers participated. All were routinely involved in making treatment decisions based on distal radius fracture radiographs. Observers performed independent repeated measurements on 30 radiographs for eight anatomical parameters: dorsal shift (mm), intra-articular gap (mm), intra-articular step (mm), palmar tilt (degrees), radial angle (degrees), radial height (mm), radial shift (mm), ulnar variance (mm). Intraclass correlation coefficients (ICCs) and the magnitude of retest errors were calculated. Measurement reliability was summarised as high (ICC > 0.80), moderate (0.60–0.80) or low (<0.60). Intra-observer reliability was high for dorsal shift and palmar tilt; moderate for radial angle, radial height, ulnar variance and radial shift; and low for intra-articular gap and step. Inter-observer reliability was high for palmar tilt; moderate for dorsal shift, ulnar variance, radial angle and radial height; and low for radial shift, intra-articular gap and step. Error magnitude (95 % confidence interval) was within 1–2 mm for intra-articular gap and step, 2–4 mm for ulnar variance, 4–6 mm for radial shift, dorsal shift and radial height, and 6–8° for radial angle and palmar tilt. Based on previous reports of critical values for palmar tilt, ulnar variance and radial angle, error margins appear small enough for measurements to be useful in guiding treatment decisions. Our findings indicate that clinicians cannot reliably measure values ≤1 mm for intra-articular gap and step when interpreting radiographic parameters using the standardised methods investigated in this study. As a guide for treatment selection, palmar tilt, ulnar variance and radial angle

Trabecular architecture of the manual elements reflects locomotor patterns in primates.

Science.gov (United States)

Matarazzo, Stacey A

2015-01-01

The morphology of trabecular bone has proven sensitive to loading patterns in the long bones and metacarpal heads of primates. It is expected that we should also see differences in the manual digits of primates that practice different methods of locomotion. Primate proximal and middle phalanges are load-bearing elements that are held in different postures and experience different mechanical strains during suspension, quadrupedalism, and knuckle walking. Micro CT scans of the middle phalanx, proximal phalanx and the metacarpal head of the third ray were used to examine the pattern of trabecular orientation in Pan, Gorilla, Pongo, Hylobates and Macaca. Several zones, i.e., the proximal ends of both phalanges and the metacarpal heads, were capable of distinguishing between knuckle-walking, quadrupedal, and suspensory primates. Orientation and shape seem to be the primary distinguishing factors but differences in bone volume, isotropy index, and degree of anisotropy were seen across included taxa. Suspensory primates show primarily proximodistal alignment in all zones, and quadrupeds more palmar-dorsal orientation in several zones. Knuckle walkers are characterized by having proximodistal alignment in the proximal ends of the phalanges and a palmar-dorsal alignment in the distal ends and metacarpal heads. These structural differences may be used to infer locmotor propensities of extinct primate taxa.

Currently available polyaxial locking plates represent the consequent enhancement of fixed-angle, first-generation locking plates. In contrast to fixed-angle locking plates which are sufficiently investigated, the strength of the new polyaxial locking options has not yet been evaluated biomechanically. This study investigates the mechanical strength of single polyaxial interfaces of different volar radius plates. Single screw-plate interfaces of the implants Palmar 2.7 (Königsee Implantate und Instrumente zur Osteosynthese GmbH, Allendorf, Germany), VariAx (Stryker Leibinger GmbH & Co. KG, Freiburg, Germany) und Viper (Integra LifeSciences Corporation, Plainsboro, NJ, USA) were tested by cantilever bending. The strength of 0 degrees, 10 degrees and 20 degrees screw locking angle was obtained during static and dynamic loading. The Palmar 2.7 interfaces showed greater ultimate strength and fatigue strength than the interfaces of the other implants. The strength of the VariAx interfaces was about 60% of Palmar 2.7 in both, static and dynamic loading. No dynamic testing was applied to the Viper plate because of its low ultimate strength. By static loading, an increase in screw locking angle caused a reduction of strength for the Palmar 2.7 and Viper locking interfaces. No influence was observed for the VariAx locking interfaces. During dynamic loading; angulation had no influence on the locking strength of Palmar 2.7. However, reduction of locking strength with increasing screw angulation was observed for VariAx. The strength of the polyaxial locking interfaces differs remarkably between the examined implants. Depending on the implant an increase of the screw locking angle causes a reduction of ultimate or fatigue strength, but not in all cases a significant impact was observed.

The artery blood supply variant of the upper limb

Science.gov (United States)

MASLARSKI, IVAN

2015-01-01

Variations of arterial patterns in the upper limb have represented the most common subject of vascular anatomy. Different types of artery branching pattern of the upper limb are very important for orthopedists in angiographic and microvascular surgical practice. The brachial artery (BA) is the most important vessel in the normal vascular anatomy of the upper limb. The classical pattern of the palmar hand region distribution shows the superficial palmar arch. Normally this arch is formed by the superficial branch of the ulnar artery and completed on the lateral side by one of these arteries: the superficial palmar branch of the radial artery, the princeps pollicis artery, the superficial palmar branch of the radial artery or the median artery. After the routine dissection of the right upper limb of an adult male cadaver, we found a very rare variant of the superficial arch artery – a division in a higher level brachial artery. We found this division at 10.4 cm from the beginning of the brachial artery. This superficial brachial artery became a radial artery and was not involved in the formation of the palm arch. In the forearm region, the artery variant was present with the median artery and the ulnar artery, which form the superficial palm arch. PMID:26733754

A sensibilidade das mãos foi avaliada por meio do kit de monofilamentos Semmes-Weinstein e, em seguida, foram aplicados três testes comumente utilizados para avaliação da função manual na seguinte ordem: teste de função manual Jebsen Taylor (TFMJT, teste dos nove pinos nos buracos (9-PnB e teste de força de preensão palmar máxima (FPmax. Os resultados do teste de sensibilidade cutânea indicaram que oito diabéticos apresentaram sensibilidade cutânea normal e cinco, alguma alteração sensorial detectável pelo monofilamento, a qual, no entanto, não os caracterizavam como neuropatas. Com relação aos testes funcionais, os resultados não indicaram qualquer diferença entre os grupos para os desempenhos nos três testes realizados (diabéticos e controles - TFMJT: 26,15±3,06 e 25,78±1,29 s; 9-PnB: 15,33±1,35 e 15,48±2,39 s; FPmax: 41,15±10,59 e 43,69±12,59 kgf. Assim, podemos concluir que indivíduos diabéticos sem neuropatia diabética periférica não apresentam qualquer alteração funcional nos membros superiores e na capacidade de gerar força de preensão palmar máxima.A successful object manipulation is crucial for living an independent life. As diabetic individuals could present sensory deficits in their hands, they could decrease functional performance in tasks

Full Text Available This study explored the immediate effects of Tai Chi (TC training on attention and meditation, perceived stress level, heart rate, oxygen saturation level in blood, and palmar skin temperature in late middle-aged adults. Twenty TC practitioners and 20 nonpractitioners volunteered to join the study. After baseline measurements were taken, the TC group performed TC for 10 minutes while their cognitive states and cardiovascular responses were concurrently monitored. The control group rested for the same duration in a standing position. Both groups were then reassessed. The participants’ attention and meditation levels were measured using electroencephalography; stress levels were measured using Perceived Stress Scale; heart rate and blood oxygenation were measured using an oximeter; and palmar skin temperature was measured using an infrared thermometer. Attention level tended to increase during TC and dropped immediately thereafter (p<0.001. Perceived stress level decreased from baseline to posttest in exclusively the TC group (p=0.005. Heart rate increased during TC (p<0.001 and decreased thereafter (p=0.001. No significant group, time, or group-by-time interaction effects were found in the meditation level, palmar skin temperature, and blood oxygenation outcomes. While a 10-minute TC training could temporarily improve attention and decrease perceived stress levels, it could not improve meditation, palmar skin temperature, or blood oxygenation among late middle-aged adults.

Full Text Available Recurrent pyogenic liver abscess since childhood is an uncommon finding in clinical medicine. Papillon-Lefèvre syndrome (PLS is a rare disease characterized by skin lesions caused by palmar-plantar hyperkeratosis, and severe periodontal destruction involving both the primary and permanent dentitions. Till date, more than 200 cases have been reported worldwide. In addition to the skin and oral findings, patients may have immune suppression and an increased susceptibility to bacteria, associated with recurrent pyogenic infections of the skin. Pyogenic liver abscess is an uncommon presentation of this rare syndrome. We present a case of PLS presenting as recurrent pyogenic liver abscess since childhood.

Full Text Available Aquagenic keratoderma has been described as a transient condition affecting predominantly young females and defined clinically by the appearance of palmar hyper-wrinkling accentuated after immersion in water. We present two new cases with aquagenic palmoplantar acrokeratoderma - a child and a young male. A significant clinical improvement was achieved after topical treatment with aluminum salts. Aquagenic palmar keratoderma may be a clue to cystic fibrosis in adolescents and young adults. We developed a new hypothesis on its pathogenesis.

2009-11-01

To investigate three-dimensional kinematics of the superficial and deep portion of triangular fibrocartilage complex (TFCC) in different parts of the forearm rotation. Six wrists of 6 volunteers were used to obtain CT scans at different positions of the wrist. The wrists were scanned from 90 degrees of pronation to 90 degrees of supination at an interval of 30 degrees. The 3-dimensional radius and ulna were reconstructed with customized software and changes in length of the superficial and deep portion of TFCC during forearm rotation. In forearm pronation, the superficial dorsal portion and the deep palmar portion of the TFCC were tight. While the superficial palmar portion and the deep dorsal potion of the TFCC were lax. In supination, the changes in length of all these fibers were reverse. In forearm rotation one portion fibers of dorsal TFCC and one portion fibers of palmar TFCC are tight, and this mechanism controls stability during DRUJ rotation.

Verdonk, René

2006-01-01

The aim of this study was to assess the radiological results of Colles’ fractures treated with Kapandji wiring and to determine the frequency of postoperative anterior fracture displacement. The X-rays of 89 fractures in women over 59 years of age were evaluated. Five weeks after injury, palmar shift of the distal fracture fragments and/or palmar tilt of more than 20° were observed in 26 patients. In ten wrists dorsal tilt was not sufficiently corrected and measured more than 10°. Increase in ulnar variance was more than 2 mm in 37 wrists and more than 5 mm in six wrists; this was more pronounced when the palmar tilt was not corrected properly or when anterior fracture displacement was present. We conclude that Kapandji wiring may not be able to prevent anterior fracture displacement in almost one-third of Colles’ fractures in osteoporotic elderly patients. PMID:16865364

Bilateral Symmetry of Distortions of Tactile Size Perception.

2015-01-01

The perceived distance between touches on the limbs is generally bigger for distances oriented across the width of the limb than for distances oriented along the length of the limb. The present study aimed to investigate the coherence of such distortions of tactile size perception across different skin surfaces. We investigated distortions of tactile size perception on the dorsal and palmar surfaces of both the left and right hands as well as the forehead. Participants judged which of two tactile distances felt larger. One distance was aligned with the proximodistal axis (along the body), the other with the mediolateral axis (across the body). Clear distortions were found on all five skin surfaces, with stimuli oriented across the width of the body being perceived as farther apart than those oriented along the length of the body. Consistent with previous results, distortions were smaller on the palmar than on the dorsal hand surface. Distortion on the forehead was intermediate between the dorsal and palmar surfaces. There were clear correlations between distortion on the left and right hands, for both the dorsal and palmar skin surfaces. In contrast, within each hand, there was no significant correlation between the two skin surfaces. Distortion on the forehead was not significantly correlated with that on any of the other skin surfaces. These results provide evidence for bilaterally symmetric representations underlying tactile size perception. © The Author(s) 2015.

Fore and hind limbs of 4-month-old Holstein-Friesian cattle ♀ (No.I) and those of 1-month-old Holstein-Friesian×Japanese Black cattle ♀ (No.II) suffering from syndactyly were dissected by means of radiographic examinations. The details were reported as follows. 1. The phalanges of both fore and left hind limbs of No.II cattle were completely fused. But, all the phalanges of left fore limb and proximal phalanges of right fore limb in No.I and the distal phalanges of right hind limb in No.II were normal, the others being of partial synostosis. 2. The distal parforating canal was absent in the metacarpus and the right metatarsus in No.II cattle. Also, in No.II on the distal part of the metacarpal or metatarsal, bone vestiges were noted, not only of the fifth and second metacarpus or metatarsus, but also the mutually jointed phalanges. 3. In No.I cattle, the left fore limb and 4 proximal sesamoid bones and 2 distal sesamoid bones, but the right limb had 4 sesamoid bones and 0 distal one. In No.II cattle, the fore limbs had 2 proximal and 0 distal sesamoid bones, left hind limb had 3 proximal and 0 distal ones, right hind limb had 3 proximal and 1 distal ones. 4. The arteries accommodated the syndactylous deformities. The median and radial arteries were fixed to be descended on to the palmar side of the metacarpus and mutually anastomosed to form a deep palmar arch. arising from the deep palmar arch, two branches (palmar proper digital aa. III and IV) were terminated by the lateral and medial palmar surfaces of the digit, where some anastomosing arches were formed by them. The arteries of the hind limbs were also similar to those of the fore limbs. 5. In radiographic examinations of syndactyly (in No.II) after 7-month feeding, hoof and digital bones were noted to have been developed, but distal phalanges were destructed and left in suspicion of bad prognosis

Polyaxial angle-stable plating is thought to be particularly beneficial in the management of complex intra-articular fractures of the distal radius. The present study was performed to investigate the strength of polyaxial locking interfaces of distal radius plates. We tested the polyaxial interfaces of 3 different distal radius plates (2.4 mm Variable Angle LCP Two-Column Volar Distal Radius Plate, Synthes, Palmar Classic, Königsee Implantate and VariAx Plate Stryker). The strength of 0° and 10° screw locking angle was obtained during static loading. The strength of Palmar Classic with a 0° locking angle is significantly the best of all tested systems. With a 10° locking angle there is no significant difference between Palmar Classic, Two column Plate and VariAx Plate. The strength of polyaxial interfaces differs between the tested systems. A reduction of ultimate strength is due to increases of screw locking angle. The design of polyaxial locking interfaces should be investigated in human bone models. © Georg Thieme Verlag KG Stuttgart · New York.

Perinatal brachial plexus palsy (PBPP) is a handicap quite commonly encountered in daily routine. Although birth trauma is considered to be the major cause of the defect, it has been observed that PBPP occurs only in some infants born under identical or nearly identical conditions. The aim of this study was to test the hypothesis of genetic predisposition for PBPP. It is well known that digito-palmar dermatoglyphs can be used to determine hereditary roots of some diseases. Thus, we found it meaningful to do a study analysis of digito-palmar dermatoglyphs in this disease as well, conducting it on 140 subjects (70 males and 70 females) diagnosed with PBPP. The control group was composed of fingerprints obtained from 400 adult and phenotypically healthy subjects (200 males and 200 females) from the Zagreb area. The results of multivariate and univariate analysis of variance have shown statistically significant differences between the groups observed. In spite of lower percentage of accurately classified female subjects by discriminant analysis, the results of quantitative analysis of digito-palmar dermatoglyphs appeared to suggest a genetic predisposition for the occurrence of PBPP.

Structural variation of the distal condyles of the third metacarpal and third metatarsal bones in the horse

Riggs, C.M.; Whitehouse, G.H.; Boyde, A.

1999-01-01

This study examined 3-dimensional (3D) distribution of sectors with contrasting density in the equine third metacarpal (McIII) and third metatarsal (MtIII) bones with a view to explaining the aetiology of distal condylar fractures. Macroradiography and computed tomographic (CT) imaging were used in the nondestructive study of bones obtained from horses, most of which were Thoroughbreds in race training. Distal condylar regions of McIII and MtIII were also studied in microradiographs of 100 mu m thick mediolateral sections cut perpendicular to the dorsal and palmar/plantar articular surfaces. Qualitative and quantitative results from all methods used (radiography, CTand microradiographic stereology) demonstrated densification (sclerosis) of subchondral bone located in the palmar/plantar regions of the medial and lateral condyles of both McIII and MtIII, Substantial density gradients between the denser condyles and the subchondral bone of the sagittal groove were shown to equate with anatomical differences in loading intensity during locomotion. It is hypothesised that such differences in bone density results in stress concentration at the palmar/plantar aspect of the condylar grooves, which may predispose to fracture

Full Text Available ABSTRACT: The carpus is a complex articulation, which is often involved in injuries in equine athletes. The objective of this study was to suggest a didactic approach for ultrasonography training for the examination of the carpal joint in horses. Ultrasonograhy examination was performed in a healthy 14-year-old horse. The images were compared with those of a dissected anatomic specimen of the carpal region of a senior horse and with those reported in the literature. Identifiable structures were as follows: (dorsal tendon of the muscle extensor carpi radialis, tendon of the muscle extensor carpi obliquus, tendon of the muscle commom digital extensor, dorsal synovial outpouchings, joint capsule and fat cushion, (lateral tendon of the muscle lateral digital extensor, lateral collateral ligament (deep and superficial components, (medial medial collateral ligament (deep and superficial components and (palmar palmar intercarpal ligament, carpal sheath, carpal tunnel, superficial digital flexor tendon, proximal origin of the deep digital flexor tendon, and palmar carpal ligament. Prior knowledge of the anatomy in combination with the study of anatomical specimens is essential for recognizing musculoskeletal structures during ultrasound examination, contributing to the training and learning processes.

Development of emotional sweating in the newborn infant.

Harpin, V A; Rutter, N

1982-09-01

Sweating from the palm and sole occurs independently of ambient temperature but is influenced by emotional factors. It thus provides a useful objective measure of emotional state. The development of this emotional sweating in the newborn was investigated by measuring palmar water loss and relating it to the infant's state of arousal. Although 433 individual measurements were made on 124 babies of gestational age 25 to 41 weeks and postnatal age 15 hours to 9 weeks. Palmar water loss was also recorded continuously in 22 infants undergoing heel prick for routine blood sampling. In babies of 37 weeks' gestation or more, there was a clear relationship between palmar water loss and arousal from the day of birth, and by the third week levels on vigorous crying were comparable with those of an anxious adult. Less mature babies did not show emotional sweating at birth; it was first seen at the equivalent of 36 to 37 weeks' gestation regardless of maturity. Continuous recordings confirmed the cross-sectional data and illustrated the abrupt nature of the response. Emotional sweating could be a useful tool for the assessment of emotional state of the newborn.

The deep lymphatic anatomy of the hand still remains the least described in medical literature. Eight hands were harvested from four nonembalmed human cadavers amputated above the wrist. A small amount of 6% hydrogen peroxide was employed to detect the lymphatic vessels around the superficial and deep palmar vascular arches, in webs from the index to little fingers, the thenar and hypothenar areas. A 30-gauge needle was inserted into the vessels and injected with a barium sulphate compound. Each specimen was dissected, photographed and radiographed to demonstrate deep lymphatic distribution of the hand. Five groups of deep collecting lymph vessels were found in the hand: superficial palmar arch lymph vessel (SPALV); deep palmar arch lymph vessel (DPALV); thenar lymph vessel (TLV); hypothenar lymph vessel (HTLV); deep finger web lymph vessel (DFWLV). Each group of vessels drained in different directions first, then all turned and ran towards the wrist in different layers. The deep lymphatic drainage of the hand has been presented. The results will provide an anatomical basis for clinical management, educational reference and scientific research. Copyright © 2018 Elsevier GmbH. All rights reserved.

2008-02-01

Full Text Available A proposta deste trabalho foi estabelecer a angiografia digital palmar como método de avaliação qualitativa in vivo da vascularização distal laminar em eqüinos em posição quadrupedal. Foram realizadas 15 angiografias de eqüinos mestiços, sendo seis machos castrados e nove fêmeas, com idade variando entre seis e oito anos. As angiografias foram realizadas, após bloqueio anestésico perineural do nervo digital palmar lateral ou medial, por meio da aplicação de 20mL de contraste na veia digital palmar lateral ou medial garroteada por atadura elástica e torniquete. Imediatamente depois, foi realizada a primeira exposição radiológica em incidência dorso-palmar. Após a dispersão do contraste, o mesmo procedimento foi realizado com o casco submetido ao tratamento térmico com água aquecida e com água resfriada. Em quatro animais, obteve-se imagem radiopaca, com bordas maldefinidas, de aspecto sombreado, ao redor de cada lâmina dérmica, que foi creditada à vasodilatação ocasionada pelo calor. Quando da vasoconstrição ocasionada pelo tratamento com frio, observou-se redução da imagem radiopaca laminar. Esse aspecto pôde ser comprovado em quatro radiografias, porém não se repetiu em todas as angiografias realizadas. Em sete radiografias, houve falha de preenchimento de contraste, o que inviabilizou a comparação entre tratamentos térmicos, sendo que as radiografias realizadas sem nenhum tratamento térmico possuíam preenchimento de contraste adequado. A angiografia digital em eqüinos mostrou-se um método sensível para evidenciar vasoconstrição e vasodilatação in vivo dentro do estojo córneo, porém inúmeros fatores podem contribuir para o aparecimento de artefatos de técnica, o que inviabiliza a comparação de alterações da perfusão laminar do casco por esse método.This study was aimed at establishing the palmar digital angiography as an in vivo qualitative method of evaluation the laminar digital

The patient-centered medical home (PCMH) model provides a compelling vision for primary care transformation, but studies of its impact have used insufficiently patient-centered metrics with inconsistent results. We propose a framework for defining patient-centered value and a new model for value-based primary care transformation: the primary care value model (PCVM). We advocate for use of patient-centered value when measuring the impact of primary care transformation, recognition, and performance-based payment; for financial support and research and development to better define primary care value-creating activities and their implementation; and for use of the model to support primary care organizations in transformation. © 2016 Annals of Family Medicine, Inc.

Serum concentrations of procollagen type III aminoterminal peptide have previously been reported to be low in some patients with primary fibromyalgia and the aim of this study was to determine if such patients differ clinically from primary fibromyalgia patients with normal levels of procollagen...... type III aminoterminal peptide. Subjective symptoms, tender points and dynamic muscle strength in 45 women with primary fibromyalgia were related to serum concentrations of procollagen type III aminoterminal peptide. Patients with low serum concentrations of procollagen type III aminoterminal peptide...... concentrations of procollagen type III aminoterminal peptide of primary fibromyalgia patients are connected to the disease impact....

Botulinum toxin

Full Text Available Botulinum toxin, one of the most poisonous biological substances known, is a neurotoxin produced by the bacterium Clostridium botulinum. C. botulinum elaborates eight antigenically distinguishable exotoxins (A, B, C 1 , C 2 , D, E, F and G. All serotypes interfere with neural transmission by blocking the release of acetylcholine, the principal neurotransmitter at the neuromuscular junction, causing muscle paralysis. The weakness induced by injection with botulinum toxin A usually lasts about three months. Botulinum toxins now play a very significant role in the management of a wide variety of medical conditions, especially strabismus and focal dystonias, hemifacial spasm, and various spastic movement disorders, headaches, hypersalivation, hyperhidrosis, and some chronic conditions that respond only partially to medical treatment. The list of possible new indications is rapidly expanding. The cosmetological applications include correction of lines, creases and wrinkling all over the face, chin, neck, and chest to dermatological applications such as hyperhidrosis. Injections with botulinum toxin are generally well tolerated and side effects are few. A precise knowledge and understanding of the functional anatomy of the mimetic muscles is absolutely necessary to correctly use botulinum toxins in clinical practice.

Full Text Available Background: Pitted keratolysis is a common dermatological condition. However, very few studies are available on the clinical characteristics and epidemiological features of this disorder from India and abroad. Materials and Methods: Fifty patients from rural area of Kolar at Sri R.L.J.H. and S.N.R. Hospital, presenting with clinically distinctive lesions of pitted keratolysis were included in the study. Cases were interviewed with particular emphasis on triggering factors and findings were recorded. Investigations like Gram′s stain, culture studies, Wood′s ultraviolet light examination, histopathology etc, was done in selected cases to ascertain the clinical diagnosis. Results: Age of the patients varied from 20 to 40 years in 52% with male preponderance in 82% of cases. Duration of the disease varied from 15 days to five years, most of the patients were bare-footed farmers (62% of cases. Hyperhidrosis and pruritus were most frequently observed symptoms in 70% and 60% of patients. Most of the patients presented with the characteristic pits which varied from 1 to 50 in number in 56 % of cases, located predominantly on the pressure bearing areas in 92% of cases and depth of the pits varied from 1 to 2 mm in 60% of cases. Associated skin conditions recorded in present study were fissuring of soles in 38%, psoriasis 10%, dermatophyte infections in 6%, planter warts 6% and Corynebacterial triad and corn in 2% of patients each. Discussion: Affection of bare-footed individuals, male preponderance, presence of hyperhidrosis and occurrence of lesions over pressure bearing areas of soles, observed in the present study were consistent with earlier studies on the subject. However, pruritus as commonest presenting symptom reported by 60% patients in the present study, has not been documented in the previous studies. Conclusion: Pitted keratolysis is fairly common in bare footed male farmers of rural India. The condition is predominantly seen over the

This study compared the efficacy between external fixator combined with palmar T-plate internal fixation and simple plate internal fixation for the treatment of comminuted distal radius fractures. A total of 61 patients classified as type C according to the AO/ASIF classification underwent surgery for comminuted distal radius fractures. There were 54 and 7 cases of closed and open fractures, respectively. Moreover, 19 patients received an external fixator combined with T-plate internal fixation, and 42 received simple plate internal fixation. All patients were treated successfully during 12-month postoperative follow-up. The follow-up results show that the palmar flexion and dorsiflexion of the wrist, radial height, and palmar angle were significantly better in those treated with the external fixator combined with T-plate compared to those treated with the simple plate only (P 0.05). Hence, the effectiveness of external fixator combined with T-plate internal fixation for the treatment of comminuted distal radius fractures was satisfactory. Patients sufficiently recovered wrist, forearm, and hand function. In conclusion, compared to the simple T-plate, the external fixator combined with T-plate internal fixation can reduce the possibility of the postoperative re-shifting of broken bones and keep the distraction of fractures to maintain radial height and prevent radial shortening.

In the rehabilitation field, the use of additive manufacturing techniques to realize customized orthoses is increasingly widespread. Obtaining a 3D model for the 3D printing phase can be done following different methodologies. We consider the creation of personalized upper limb orthoses, also including fingers, starting from the acquisition of the hand geometry through accurate 3D scanning. However, hand scanning procedure presents differences between healthy subjects and patients affected by pathologies that compromise upper limb functionality. In this work, we present the concept and design of a 3D printed support to assist hand scanning of such patients. The device, realized with FDM additive manufacturing techniques in ABS material, allows palmar acquisitions, and its design and test are motivated by the following needs: (1) immobilizing the hand of patients during the palmar scanning to reduce involuntary movements affecting the scanning quality and (2) keeping hands open and in a correct position, especially to contrast the high degree of hypertonicity of spastic subjects. The resulting device can be used indifferently for the right and the left hand; it is provided in four-dimensional sizes and may be also suitable as a palmar support for the acquisition of the dorsal side of the hand.

Full Text Available Dupuytren’s disease (palmar fibromatosis involves nodules in fascia of the hand that leads to flexion contractures. Ledderhose disease (plantar fibromatosis is similar with nodules of the foot. While clinical aspects are well-described, genetic mechanisms are unknown. We report a family with cardiac disease due to a heterozygous LMNA mutation (c.736C>T, p.Gln246Stop with palmar/plantar fibromatosis and investigate the hypothesis that a second rare DNA variant increases the risk for fibrotic disease in LMNA mutation carriers. The proband and six family members were evaluated for the cardiac and hand/feet phenotypes and tested for the LMNA mutation. Fibroblast RNA studies revealed monoallelic expression of the normal LMNA allele and reduced lamin A/C mRNAs consistent with LMNA haploinsufficiency. A novel, heterozygous missense variant (c.230T>C, p.Val77Ala in the Asteroid Homolog 1 (ASTE1 gene was identified as a potential risk factor in fibrotic disease using exome sequencing and family studies of five family members: four LMNA mutation carriers with fibromatosis and one individual without the LMNA mutation and no fibromatosis. With a possible role in epidermal growth factor receptor signaling, ASTE1 may contribute to the increased risk for palmar/plantar fibromatosis in patients with Lamin A/C haploinsufficiency.

It is rare for one human being to be afflicted with more than one cancer. However with further advances in therapeutic regimens, histopathologic observation, diagnostic modalities, and increased curiosity, there are increasing number of case reports of multiple primary cancer. The present study evaluates 25 histologically confirmed cases of multiple primary cancer from 1974 to 1988 at Kosin Medical Center. The most frequent site of the first primary cancer in male was stomach and in female, uterine cervix. The first primary cancer in female occurred in endocrine-related organs (breast, uterus and thyroid) in 63.6 percent. Synchronous cancers are diagnosed simultaneously or within an interval of about six months and synchronous cancers were 16 out of 25 cases. Metachronous cancers are diagnosed at interval of more than six months. There were 9 metachronous cancers and average interval between the first and second primary cancer was 22.8 months. The incidence of multiple primary cancer was 0.11 percent. The average age was 51.9 years at the time of the first primary cancer (53.1 years in male and 50.3 years in female). CT scan was most helpful in early detection of multiple primary cancers facilitating biopsy and surgery. Multiple primary cancers are beyond the medical curiosity. Early diagnosis of the disease and careful follow-up study, based on an awareness of the possibility of second cancers, will substantially increase the survival of these patients

Normocalcemic Primary Hyperparathyroidism

Cusano, Natalie E.; Silverberg, Shonni J.; Bilezikian, John P.

2013-01-01

Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of hyperparathyroidism, such as renal disease or vitamin D deficiency. Recognition of this phenotype of primary hyperparathyroidism, normocalcemic primary hyperparathyroidism, supports a biphasic chronological time course in some individuals in which PTH levels are first elevated but serum calcium is normal, followed by the development of frank hypercalcemia. This review focuses on the available literature regarding this newly described phenotype of primary hyperparathyroidism. PMID:23374739

2008-12-01

Full Text Available Abstract Background Primary care internationally is approaching a new paradigm. The change agenda implicit in this threatens to de-stabilise and challenge established general practice and primary care. Discussion The Primary Care Amplification Model offers a means to harness the change agenda by 'amplifying' the strengths of established general practices around a 'beacon' practice. Conclusion Such 'beacon' practices can provide a mustering point for an expanded scope of practice for primary care, integrated primary/secondary service delivery, interprofessional learning, relevant local clinical research, and a focus on local service innovation, enhancing rather than fragmenting the collective capacity of existing primary care.

Hamza, Doha R.

2014-06-01

We consider a spectrum-sharing system, where the primary terminal operates in a time-slotted fashion and is active only when it has a packet to send. The secondary terminal uses spectrum sensing results and the primary automatic repeat request (ARQ) feedback to access the channel probabilistically. To enhance the primary\\'s system performance, the secondary user (SU) acts as a relay for the primary user (PU) in the event of transmission failure on the direct link of the latter. Closed-form expressions for the primary and secondary throughputs are obtained for the described scheme. The optimal medium access probabilities are then obtained by maximizing the secondary throughput subject to constraints that guarantee the stability of the considered queues, a minimum primary throughput, and a maximum primary queueing delay. The results clearly indicate the benefits of cognitive relaying in enhancing the throughput performance for both the PU and SU. Furthermore, by guaranteeing minimum rate and maximum delay requirements, our scheme is shown to provide a definitive notion of protection for the licensed users of the network. © 2013 IEEE.

Full Text Available Background. Primary ovarian malignant melanoma is extremely rare. It usually appears in the wall of a dermoid cyst or is associated with another teratomatous component. Metastatic primary malignant melanoma to ovary from a primary melanoma elsewhere is well known and has been often reported especially in autopsy studies. Case report. We presented a case of primary ovarian malignant melanoma in a 45- year old woman, with no evidence of extraovarian primary melanoma nor teratomatous component. The tumor was unilateral, macroscopically on section presented as solid mass, dark brown to black color. Microscopically, tumor cells showed positive immunohistochemical reaction for HMB-45, melan-A and S-100 protein, and negative immunoreactivity for estrogen and progesteron receptors. Conclusion. Differentiate metastatic melanoma from rare primary ovarian malignant melanoma, in some of cases may be a histopathological diagnostic problem. Histopathological diagnosis of primary ovarian malignant melanoma should be confirmed by immunohistochemical analyses and detailed clinical search for an occult primary tumor.

Objective To evaluate efficacy and safety of botulinum toxin type B (BTX-B) in treatment of movement disorders including blepharospasm, oromandibular dystonia, hemifacial spasm, tremor, tics, and hypersecretory disorders such as sialorrhea and hyperhidrosis.Methods A retrospective study of BTX-B injections in treatment of 58 patients with various neurological disorders was performed. The mean follow-up time was 0.9 ± 0.8 years. Results of the first and last treatment of patients with at least 3injection sessions were compared.Results The response of 58 patients to a total of 157 BTX-B treatment sessions was analyzed. Of the 157 treatment sessions, 120 sessions (76.4%) resulted in moderate or marked improvement while 17 sessions (10.8%) had no response.The clinical benefits after BTX-B treatment lasted an average of 14 weeks. Of the 41 patients with at least 3 injection sessions (mean 10 ± 8.6), most patients needed increased dosage upon the last session compared to the first session. Nineteen patients (32.8%) with 27 sessions (17.2%) reported adverse effects with BTX-B treatment.Conclusios Though most patients require increased dosage to maintain effective response after repeated injections,BTX-B is an effective and safe treatment drug for a variety of movement disorders, as well as drooling and hyperhidrosis.

Odonto-onycho-dermal dysplasia (OODD) is a rare form of ectodermal dysplasia characterized by severe oligodontia, onychodysplasia, palmoplantar hyperkeratosis, dry skin, hypotrichosis, and hyperhidrosis of the palms and soles. The ectodermal dysplasias resulting from biallelic mutations in the WNT10A gene result in highly variable phenotypes, ranging from isolated tooth agenesis to OODD and Schöpf-Schulz-Passarge syndrome (SSPS). We identified a female patient, with consanguineous parents, who was clinically diagnosed with OODD. Genetic testing showed that she was homozygous for a previously reported pathogenic mutation in the WNT10A gene, c.321C > A, p.Cys107*. The skin and nail abnormalities were for many years interpreted as psoriasis and treated accordingly. A thorough clinical examination revealed hypotrichosis and hyperhidrosis of the soles and dental examination revealed agenesis of permanent teeth except the two maxillary central incisors. Skin biopsies from the hyperkeratotic palms and soles showed the characteristic changes of eccrine syringofibroadenomatosis, which has been described in patients with ectodermal dysplasias. Together with a family history of tooth anomalies, this lead to the clinical suspicion of a hereditary ectodermal dysplasia. This case illustrates the challenges of diagnosing ectodermal dysplasia like OODD and highlights the relevance of interdisciplinary cooperation in the diagnosis of rare conditions.

Many commissural reconstruction techniques have been described for the treatment of syndactyly. This study is the first to compare long-term results of 2 commissural dorsal flap procedures (T-flap and omega-flap). Fifty-nine web-spaces in 39 patients, operated on between 1991 and 2008, were retrospectively analyzed. Thirty-six T-flap and 23 omega-flap procedures were performed using full-thickness skin graft in every case for digital resurfacing. Factors that could affect the long-term outcome were collected, including development of web-creep, clinodactyly, and flexion contracture. Patients were reviewed with a mean follow-up of 5 years and 8 months. Preoperative complexity of syndactyly influenced the development of clinodactyly and flexion contracture. Among the patients who developed clinodactyly, 96% had surgery for complex syndactyly. No difference was found between the 2 flap methods concerning digital deformation and mobility. However, web-creep occurred more frequently after T-flap than after omega-flap procedures (17% vs. 5%). The combination of either dorsal commissural T-flaps or omega-flaps with full-thickness graft to resurface digits is a reliable technique for the treatment of syndactyly with satisfactory functional and cosmetic results. Long-term results are not influenced by the type of flap. Nevertheless, the omega-flap technique, using 2 triangular lateral-palmar flaps, avoids use of skin graft to cover lateral-palmar aspects of the new commissure, consequently reducing the incidence of web-creep. In cases of syndactyly, the primary prognostic factor is whether the patient has simple or complex syndactyly. In complex syndactyly, the risk of long-term unfavorable results is higher. When complex complicated syndactyly is involved, postoperative complication rates increase. Level III.

Full Text Available The Dual Visuomotor Channel Theory proposes that visually guided reaching is a composite of two movements, a Reach that advances the hand to contact the target and a Grasp that shapes the digits for target purchase. The theory is supported by biometric analyses of adult reaching, evolutionary contrasts, and differential developmental patterns for the Reach and the Grasp in visually guided reaching in human infants. The present ethological study asked whether there is evidence for a dissociated development for the Reach and the Grasp in nonvisual hand use in very early infancy. The study documents a rich array of spontaneous self-touching behavior in infants during the first six months of life and subjects the movements to analyses of body target, contact type, and Grasp. Video recordings were made of resting alert infants biweekly from birth to 6 months. In younger infants, self-touching targets included the head and trunk. As infants aged, targets became more caudal including the hips, legs, and feet. In younger infants hand contact was mainly made with the dorsum of the hand, but as infants aged contacts included palmar and eventually grasp and manipulatory contacts with the body and clothes. The relative incidence of caudal contacts and palmar contacts increased concurrently and were significantly correlated throughout the period of study. In contrast, developmental increases in self grasping emerged a few weeks after the increases observed in caudal and palmar contacts. The behavioral and temporal pattern of these spontaneous self-touching movements suggest that the Reach, in which the hand extends to make a palmar self-contact, and the Grasp, in which the digits close and make manipulatory movements, have partially independent developmental profiles. The results additionally suggest that self-touching behavior is an important developmental phase that allows for the coordination of the Reach and the Grasp prior to their use under visual

Full Text Available The ′Other Primary Headaches′ include eight recognised benign headache disorders. Primary stabbing headache is a generally benign disorder which often co-exists with other primary headache disorders such as migraine and cluster headache. Primary cough headache is headache precipitated by valsalva; secondary cough has been reported particularly in association with posterior fossa pathology. Primary exertional headache can occur with sudden or gradual onset during, or immediately after, exercise. Similarly headache associated with sexual activity can occur with gradual evolution or sudden onset. Secondary headache is more likely with both exertional and sexual headache of sudden onset. Sudden onset headache, with maximum intensity reached within a minute, is termed thunderclap headache. A benign form of thunderclap headache exists. However, isolated primary and secondary thunderclap headache cannot be clinically differentiated. Therefore all headache of thunderclap onset should be investigated. The primary forms of the aforementioned paroxysmal headaches appear to be Indomethacin sensitive disorders. Hypnic headache is a rare disorder which is termed ′alarm clock headache′, exclusively waking patients from sleep. The disorder can be Indomethacin responsive, but can also respond to Lithium and caffeine. New daily persistent headache is a rare and often intractable headache which starts one day and persists daily thereafter for at least 3 months. The clinical syndrome more often has migrainous features or is otherwise has a chronic tension-type headache phenotype. Management is that of the clinical syndrome. Hemicrania continua straddles the disorders of migraine and the trigeminal autonomic cephalalgias and is not dealt with in this review.

There is a growing interest in the sleep habits of children affected by PNE, which is derived from the contradictory data present in clinical literature. The aim of the present study was to evaluate the presence of sleep disturbances in a population of children affected by PNE, and to identify whether PNE could be considered as a risk factor for sleep disturbances among children.Materials and methods: A total of 190 PNE children (97 males, 93 females aged 7–15 years, (mean 9.64 ± 1.35 years, and 766 typically developing children matched for age (P = 0.131 and gender (P = 0.963 were enrolled. To evaluate the presence of sleep habits and disturbances, all of the subjects’ mothers filled out the Sleep Disturbances Scale for Children (SDSC, a questionnaire consisting of six subscales: Disorders in Initiating and Maintaining Sleep (DIMS, Sleep Breathing Disorders (SBD, Disorders of Arousal (DA, Sleep–Wake Transition Disorders (SWTD, Disorders of Excessive Somnolence (DOES, and Nocturnal Hyperhidrosis (SHY.

Workforce projections indicate a potential shortage of up to 31,000 adult primary care providers by the year 2025. Approximately 80 % of internal medicine residents and nearly two-thirds of primary care internal medicine residents do not plan to have a career in primary care or general internal medicine. We aimed to explore contextual and programmatic factors within primary care residency training environments that may influence career choices. This was a qualitative study based on semi-structured, in-person interviews. Three primary care internal medicine residency programs were purposefully selected to represent a diversity of training environments. Second and third year residents were interviewed. We used a survey guide developed from pilot interviews and existing literature. Three members of the research team independently coded the transcripts and developed the code structure based on the constant comparative method. The research team identified emerging themes and refined codes. ATLAS.ti was used for the analysis. We completed 24 interviews (12 second-year residents, and 12 third-year residents). The age range was 27-39 years. Four recurrent themes characterized contextual and programmatic factors contributing to residents' decision-making: resident expectations of a career in primary care, navigation of the boundary between social needs and medical needs, mentorship and perceptions of primary care, and structural features of the training program. Addressing aspects of training that may discourage residents from careers in primary care such as lack of diversity in outpatient experiences and resident frustration with their inability to address social needs of patients, and strengthening aspects of training that may encourage interests in careers in primary care such as mentorship and protected time away from inpatient responsibilities during primary care rotations, may increase the proportion of residents enrolled in primary care training programs who pursue

Kitchell, R L; Canton, D D; Johnson, R D; Maxwell, S A

1982-10-01

The cutaneous innervation of the forelimb was investigated in 20 barbiturate-anesthetized cats by using electrophysiological techniques. The cutaneous area (CA) innervated by each cutaneous nerve was delineated in at least six cats by brushing the hair in the CA with a small watercolor brush while recording from the nerve. Mapping of adjacent CA revealed larger overlap zones (OZ) than were noted in the dog. Remarkable findings were that the brachiocephalic nerve arose from the axillary nerve and the CA comparable to that supplied by the cutaneous branch of the brachiocephalic nerve in the dog was supplied by a cutaneous branch of the suprascapular nerve. The CA supplied by the communicating branch from the musculocutaneous to the median nerve was similar in both species except that the communicating branch arose proximal to any other branches of the musculocutaneous nerve in the cat, whereas it was a terminal branch in the dog. The superficial branch of the radial nerve gave off cutaneous brachial branches in the cat proximal to the lateral cutaneous antebrachial nerve. The CA of the palmar branches of the ulnar nerve did not completely overlap the CA of the palmar branches of the median nerve as occurred in the dog; thus an autonomous zone (AZ) for the CA of the palmar branches of the median nerve is present in the cat, whereas no AZ existed for the CA of this nerve in the dog.

Full Text Available OBJECTIVES: Noonan and Noonan-related syndromes are common autosomal dominant disorders with neuro-cardio-facial-cutaneous and developmental involvement. The objective of this article is to describe the most relevant tegumentary findings in a cohort of 41 patients with Noonan or Noonan-related syndromes and to detail certain aspects of the molecular mechanisms underlying ectodermal involvement. METHODS: A standard questionnaire was administered. A focused physical examination and a systematic review of clinical records was performed on all patients to verify the presence of tegumentary alterations. The molecular analysis of this cohort included sequencing of the following genes in all patients: PTPN1, SOS1, RAF1, KRAS, SHOC2 and BRAF. RESULTS: The most frequent tegumentary alterations were xeroderma (46%, photosensitivity (29%, excessive hair loss (24%, recurrent oral ulcers (22%, curly hair (20%, nevi (17%, markedly increased palmar and plantar creases (12%, follicular hyperkeratosis (12%, palmoplantar hyperkeratosis (10%, café-au-lait spots (10% and sparse eyebrows (7%. Patients with mutations in PTPN11 had lower frequencies of palmar and plantar creases and palmar/plantar hyperkeratosis compared with the other patients. CONCLUSIONS: We observed that patients with mutations in genes directly involved in cell proliferation kinase cascades (SOS1, BRAF, KRAS and RAF1 had a higher frequency of hyperkeratotic lesions compared with patients with mutations in genes that have a more complex interaction with and modulation of cell proliferation kinase cascades (PTPN11.

Full Text Available The aim of the present work was to study the deltamethrin susceptibility of eggs from Triatoma infestans populations and the contribution of pyrethroid esterases to deltamethrin degradation. Insects were collected from sylvatic areas, including Veinte de Octubre and Kirus-Mayu (Bolivia and from domiciliary areas, including El Palmar (Bolivia and La Pista (Argentina. Deltamethrin susceptibility was determined by dose-response bioassays. Serial dilutions of deltamethrin (0.0005-1 mg/mL were topically applied to 12-day-old eggs. Samples from El Palmar had the highest lethal dose ratio (LDR value (44.90 compared to the susceptible reference strain (NFS, whereas the Veinte de Octubre samples had the lowest value (0.50. Pyrethroid esterases were evaluated using 7-coumaryl permethrate (7-CP on individually homogenised eggs from each population and from NFS. The El Palmar and La Pista samples contained 40.11 and 36.64 pmol/min/mg protein, respectively, and these values were statistically similar to NFS (34.92 pmol/min/mg protein and different from Kirus-Mayu and Veinte de Octubre (27.49 and 22.69 pmol/min/mg protein, respectively. The toxicological data indicate that the domestic populations were resistant to deltamethrin, but no statistical contribution of 7-CP esterases was observed. The sylvatic populations had similar LDR values to NFS, but lower 7-CP esterase activities. Moreover, this is the first study of the pyrethroid esterases on T. infestans eggs employing a specific substrate (7-CP.

Primary prevention of chronic obstructive pulmonary disease in primary care.

Science.gov (United States)

van der Molen, Thys; Schokker, Siebrig

2009-12-01

Chronic obstructive pulmonary disease (COPD) is a prevalent disease, with cigarette smoking being the main risk factor. Prevention is crucial in the fight against COPD. Whereas primary prevention is targeted on whole populations, patient populations are the focus of primary care; therefore, prevention in this setting is mainly aimed at preventing further deterioration of the disease in patients who present with the first signs of disease (secondary prevention). Prevention of COPD in primary care requires detection of COPD at an early stage. An accurate definition of COPD is crucial in this identification process. The benefits of detecting new patients with COPD should be determined before recommending screening and case-finding programs in primary care. No evidence is available that screening by spirometry results in significant health gains. Effective treatment options in patients with mild disease are lacking. Smoking cessation is the cornerstone of COPD prevention. Because cigarette smoking is not only a major cause of COPD but is also a major cause of many other diseases, a decline in tobacco smoking would result in substantial health benefits.

Bilateral supernumerary primary maxillary canines

Directory of Open Access Journals (Sweden)

Santanu Mukhopadhyay

2018-01-01

Full Text Available Supernumerary teeth are more common in the permanent than in primary dentition. In the primary dentition, the anomaly is most frequently observed in the maxillary lateral incisor region, followed by the maxillary midline where they are termed as mesiodens. Supernumerary teeth in the primary canine region are rare. This paper describes a rare case of nonsyndromic supernumerary primary maxillary canine distributed bilaterally in a 4-year-old boy. Both the supernumeraries resembled size and shape of normal primary canine. The right supplemental canine is high labially placed, whereas the left one is seen normally aligned in the dental arch distal to lateral incisor. One of the most significant sequelae of primary supernumerary teeth is their duplication in the permanent series. Radiographic examination of supernumerary primary canine did not indicate any such anomaly in the permanent dentition. The patient was kept under observation.

Radiotherapy in fascial fibromatosis: a case series, literature review and considerations for treatment of early-stage disease

International Nuclear Information System (INIS)

Grenfell, Solveig; Borg, Martin

2014-01-01

Palmar and plantar fascial fibromatoses are benign hyperproliferative disorders of the deep fascia of the palm and sole. This study seeks to examine the role of radiotherapy in the management of fascial fibromatosis. Six consecutive cases of early-stage fascial fibromatosis treated with radiotherapy at the Adelaide Radiotherapy Centre between July 2008 and May 2011 were analysed. The results of the case series were compared with a systematic review of the literature. All six cases regressed or showed a reduction of symptoms following radiotherapy. Treatment was well tolerated with minor toxicities. Median follow-up for the case series was 38.5 months. The systematic review identified seven studies describing the use of radiotherapy as primary treatment for fascial fibromatosis between 1946 and 2013. The literature indicates that radiotherapy can prevent disease progression and improve symptoms for early-stage disease, with low likelihood of significant toxicities. Early results from our case series are consistent with the literature, showing that radiotherapy can provide an effective management option for patients with early-stage fascial fibromatosis, and justify consideration of radiotherapy as a primary treatment for early-stage disease.

Influence of hydrazine primary water chemistry on corrosion of fuel cladding and primary circuit components

1999-01-01

Earlier at Paks 1-4 NPP standard ammonia chemistry was in use. The following station performance indicators were improved when hydrazine primary water chemistry was introduced: occupational radiation exposures of personnel; gamma-radiation dose rates near primary system components during refuelling and maintenance outages. The reduction of radiation exposures and radiation fields were achieved without significant expenses. Recent results of experimental studies allowed to explain the mechanism of hydrazine dosing influence on: corrosion rate of structure materials in primary coolant; behaviour of soluble and insoluble corrosion products including long-life corrosion-induced radionuclides in primary system during steady-state and transient operation modes; radiolytic generation of oxidising radiolytic products in core and its corrosion activity in primary system; radiation situation during refuelling and maintenance outages; foreign material degradation and removal (including corrosion active oxidant species) from primary system during abnormal events. Operational experience and experimental data have shown that hydrazine primary water chemistry allows to reduce corrosion wear and thereby makes it possible to extend the life-time of plant components in primary system.

Neuropeptides, neurogenic inflammation and complex regional pain syndrome (CRPS).

Science.gov (United States)

Birklein, Frank; Schmelz, Martin

2008-06-06

This review explains symptoms and nature of neuropeptide signaling and its importance for clinical symptoms of CRPS. Neurogenic inflammation regularly accompanies excitation of primary afferent nociceptors. It has two major components-plasma extravasation and vasodilatation. The most important mediators are the calcitonin gene-related peptide (CGRP) and substance P (SP). After peripheral trauma immune reaction (e.g. cytokines) and the attempts of the tissue to regenerate (e.g. growth factors) sensitize nociceptors and amplify neurogenic inflammation. This cascade of events has been demonstrated in rat models of CRPS. Clinical findings in these animals strongly resemble clinical findings in CRPS, and can be prevented by anti-cytokine and anti-neuropeptide treatment. In CRPS patients, there is meanwhile also plenty of evidence that neurogenic inflammation contributes to clinical presentation. Increased cytokine production was demonstrated, as well as facilitated neurogenic inflammation. Very recently even "non-inflammatory" signs of CRPS (hyperhidrosis, cold skin) have been linked to neuropeptide signaling. Surprisingly, there was even moderately increased neurogenic inflammation in unaffected body regions. This favors the possibility that CRPS patients share genetic similarities. The future search for genetic commonalities will help us to further unravel the "mystery" CRPS.

Studies on topical antiperspirant control of axillary hyperhidrosis.

Science.gov (United States)

Shelley, W B; Hurley, H J

1975-01-01

Axillary hyperhidrotics is reviewed from the standpoint of anatomical factors, physiological mechanisms and the history of methods of control. Anhydrous aluminum chloride and anhydrous zirconium tetrachloride are shown to be superior topical agents for partial control of axillary sweating when applied as a powder or in anhydrous nonreactive vehicles. Complete anhidrosis as demonstrated by sustained garment armpit dryness could be achieved in hyperhidrotics within 48 hours by the following trinary antiperspirant system: (1) a saturated solution of aluminum chloride hexahydrate or zirconyl chloride in absolute ethanol or isopropyl alcohol, (2) application to the dry axilla at times of sleep or other prolonged non-sweating period, (3) water vapor occlusion of area for 6 to 8 hours by means of Saran wrap. The hypothesis is presented that metallic antiperspirants act by reflux entrance into the terminal intraepidermal eccrine duct, slowly combining with the intraductal keratin, to produce a fibrillar contraction (super contraction) of keratin and hence functional closure, not histologically evident. This altered keratin is shed weeks later, with the consequent return of ductal patency and sweating.

Primary black holes

International Nuclear Information System (INIS)

Novikov, I.; Polnarev, A.

1981-01-01

Proves are searched for of the formation of the so-called primary black holes at the very origin of the universe. The black holes would weigh less than 10 13 kg. The formation of a primary black hole is conditional on strong fluctuations of the gravitational field corresponding roughly to a half of the fluctuation maximally permissible by the general relativity theory. Only big fluctuations of the gravitational field can overcome the forces of the hot gas pressure and compress the originally expanding matter into a black hole. Low-mass black holes have a temperature exceeding that of the black holes formed from stars. A quantum process of particle formation, the so-called evaporation takes place in the strong gravitational field of a black hole. The lower the mass of the black hole, the shorter the evaporation time. The analyses of processes taking place during the evaporation of low-mass primary black holes show that only a very small proportion of the total mass of the matter in the universe could turn into primary black holes.

This study further evaluated a computer-based infrared thermography (IRT) system, which employs artificial neural networks for the diagnosis of carpal tunnel syndrome (CTS) using a large database of 502 thermal images of the dorsal and palmar side of 132 healthy and 119 pathological hands. It confirmed the hypothesis that the dorsal side of the hand is of greater importance than the palmar side when diagnosing CTS thermographically. Using this method it was possible correctly to classify 72.2% of all hands (healthy and pathological) based on dorsal images and > 80% of hands when only severely affected and healthy hands were considered. Compared with the gold standard electromyographic diagnosis of CTS, IRT cannot be recommended as an adequate diagnostic tool when exact severity level diagnosis is required, however we conclude that IRT could be used as a screening tool for severe cases in populations with high ergonomic risk factors of CTS.

We present an anatomic study of the vein distribution at the eponychial level, in order to standardize outpatient fingertip replantation. The cross sectional anatomy of 100 fingers was studied by dissection following dye injection. The distribution of the veins >0.3 mm was recorded on a pie-chart. Thirty fingers in 27 patients with fingertip amputations at the eponychial level were replanted by anastomosis of the palmar subcutaneous veins, to reconstruct the venous reflux of the amputated digits. The operations were aided by the anatomical study and confirmed that the palmar area is the preferred site for venous anastomosis Following a distal finger amputation at the level of the eponychial fold we propose starting the search for veins between the 3 to 5 o'clock or 7 to 9 o'clock positions, as these are the areas where there are most likely to be suitable veins.

HIGH ORIGIN OF SUPERFICIAL ULNAR ARTERY- A CASE REPORT

Directory of Open Access Journals (Sweden)

Anjana Jayakumaran Nair

2017-03-01

Full Text Available BACKGROUND High origin and superficially placed ulnar artery is a rare anatomical variant that usually arises either in the axilla or arm and runs a superficial course in the forearm, enters the hand and participates in the formation of superficial palmar arch. During routine dissection of cadavers in our department, we observed a unilateral case of high origin and superficial ulnar artery in a human male cadaver. It originated from the brachial artery in the lower third of arm 4 cm above its bifurcation. From its origin, it passed downwards along the medial aspect of forearm, superficial to the flexors, entered hand superficial to the flexor retinaculum and formed superficial palmar arch. The knowledge of existence of a superficial ulnar artery is important during vascular and reconstructive surgery and also in evaluation of angiographic images. Superficial position makes it more vulnerable to trauma and more accessible to cannulation.

During the past few decades of astrocyte research it has become increasingly clear that astrocytes have taken a central position in all central nervous system activities. Much of our new understanding of astrocytes has been derived from studies conducted with primary cultures of astrocytes...... subsequently found in vivo. Nevertheless, primary cultures of astrocytes are an in vitro model that does not fully mimic the complex events occurring in vivo. Here we present an overview of the numerous contributions generated by the use of primary astrocyte cultures to uncover the diverse functions...... of astrocytes. Many of these discoveries would not have been possible to achieve without the use of astrocyte cultures. Additionally, we address and discuss the concerns that have been raised regarding the use of primary cultures of astrocytes as an experimental model system....

Functional classification of grasp strategies used by hemiplegic patients.

Full Text Available This study aimed to identify and qualify grasp-types used by patients with stroke and determine the clinical parameters that could explain the use of each grasp. Thirty-eight patients with chronic stroke-related hemiparesis and a range of motor and functional capacities (17 females and 21 males, aged 25-78, and 10 healthy subjects were included. Four objects were used (tissue packet, teaspoon, bottle and tennis ball. Participants were instructed to "grasp the object as if you are going to use it". Three trials were video-recorded for each object. A total of 456 grasps were analysed and rated using a custom-designed Functional Grasp Scale. Eight grasp-types were identified from the analysis: healthy subjects used Multi-pulpar, Pluri-digital, Lateral-pinch and Palmar grasps (Standard Grasps. Patients used the same grasps with in addition Digito-palmar, Raking, Ulnar and Interdigital grasps (Alternative Grasps. Only patients with a moderate or relatively good functional ability used Standard grasps. The correlation and regression analyses showed this was conditioned by sufficient finger and elbow extensor strength (Pluri-digital grasp; thumb extensor and wrist flexor strength (Lateral pinch or in forearm supinator strength (Palmar grasp. By contrast, the patients who had severe impairment used Alternative grasps that did not involve the thumb. These strategies likely compensate specific impairments. Regression and correlation analyses suggested that weakness had a greater influence over grasp strategy than spasticity. This would imply that treatment should focus on improving hand strength and control although reducing spasticity may be useful in some cases.

Fractures of the distal phalanx and associated soft tissue and osseous abnormalities in 22 horses with ossified sclerotic ungual cartilages diagnosed with magnetic resonance imaging.

Ungual cartilage ossification in the forelimb is a common finding in horses. Subtle abnormalities associated with the ungual cartilages can be difficult to identify on radiographs. Magnetic resonance (MR) imaging findings of 22 horses (23 forelimbs) with a fracture of the distal phalanx and ossified ungual cartilage were characterized and graded. All horses had a forelimb fracture. Eleven involved a left forelimb (seven medial; four lateral), and 12 involved a right forelimb (five medial; seven lateral). All fractures were nonarticular, simple in configuration, and nondisplaced. The fractures were oriented in an axial proximal to abaxial distal and palmar to dorsal direction, and extended from the base of the ossified ungual cartilage into the distal phalanx. The fracture involved the fossa of the collateral ligament on the distal phalanx in 17 of 23 limbs. The palmar process and ossified ungual cartilage was abnormally mineralized in all horses. Ligaments and soft tissues adjacent to the ossified ungual cartilages were affected in all horses. The routine site of fracture in this study at the base of the ossified ungual cartilage extending into the distal phalanx suggests a biomechanical cause or focal stress point from cycling. The ligamentous structures associated with the ungual cartilages were often affected, showed altered signal intensity as well as enlargement and were thought to be contributing to the lameness. In conclusion, ossified ungual cartilages may lead to fracture of the palmar process of the distal phalanx and injury of the ungual cartilage ligaments. © 2011 Veterinary Radiology & Ultrasound.

Median artery of the forearm in human fetuses in northeastern Brazil: anatomical study and review of the literature.

Science.gov (United States)

Aragão, José Aderval; da Silva, Ana Caroline Ferreira; Anunciação, Caio Barretto; Reis, Francisco Prado

A persistent median artery is a rare anomaly. It accompanies the median nerve along its course in the forearm and is of variable origin. It is associated with other local anatomical variations and may contribute significantly towards formation of the superficial palmar arch. In embryos, it is responsible mainly for the blood supply to the hand. The objective of this study was to research the frequency, type (forearm or palmar) and origin of the median artery in fetuses, correlating its presence with sex and body side. Red-colored latex was injected into 32 brachial arteries of human fetuses until its arrival in the hand could be seen. Twenty-four hours after the injection, the median arteries were dissected without the aid of optical instruments. Among the 32 forearms dissected, the median artery was present in 81.25 % (26) of the cases, and it was found more frequently in females and on the left side. Regarding origin, most of the median arteries originated in the common interosseous artery (38.5 %) and anterior interosseous artery (34.6 %). The mean length of the median arteries was 21.1 mm for the palmar type and 19.8 mm for the forearm type. The median artery has a high rate of persistence. It is important to be aware of this anatomical variation, since its presence may give rise to difficulties during routine surgical procedures on the wrist. Its presence may cause serious functional complications in the carpal tunnel, anterior interosseous nerve, round pronator syndromes, and ischemia of the hand.

The Coming Primary Care Revolution.

Science.gov (United States)

Ellner, Andrew L; Phillips, Russell S

2017-04-01

The United States has the most expensive, technologically advanced, and sub-specialized healthcare system in the world, yet it has worse population health status than any other high-income country. Rising healthcare costs, high rates of waste, the continued trend towards chronic non-communicable disease, and the growth of new market entrants that compete with primary care services have set the stage for fundamental change in all of healthcare, driven by a revolution in primary care. We believe that the coming primary care revolution ought to be guided by the following design principles: 1) Payment must adequately support primary care and reward value, including non-visit-based care. 2) Relationships will serve as the bedrock of value in primary care, and will increasingly be fostered by teams, improved clinical operations, and technology, with patients and non-physicians assuming an ever-increasing role in most aspects of healthcare. 3) Generalist physicians will increasingly focus on high-acuity and high-complexity presentations, and primary care teams will increasingly manage conditions that specialists managed in the past. 4) Primary care will refocus on whole-person care, and address health behaviors as well as vision, hearing, dental, and social services. Design based on these principles should lead to higher-value healthcare, but will require new approaches to workforce training.

Although there is widespread agreement on health- and cost-related benefits of strong primary care in health systems, little is known about the development of the primary care status over time in specific countries, especially in countries with a traditionally weak primary care sector such as Switzerland. The aim of our study was to assess the current strength of primary care in the Swiss health care system and to compare it with published results of earlier primary care assessments in Switzerland and other countries. A survey of experts and stakeholders with insights into the Swiss health care system was carried out between February and March 2014. The study was designed as mixed-modes survey with a self-administered questionnaire based on a set of 15 indicators for the assessment of primary care strength. Forty representatives of Swiss primary and secondary care, patient associations, funders, health care authority, policy makers and experts in health services research were addressed. Concordance between the indicators of a strong primary care system and the real situation in Swiss primary care was rated with 0-2 points (low-high concordance). A response rate of 62.5% was achieved. Participants rated concordance with five indicators as 0 (low), with seven indicators as 1 (medium) and with three indicators as 2 (high). In sum, Switzerland achieved 13 of 30 possible points. Low scores were assigned because of the following characteristics of Swiss primary care: inequitable local distribution of medical resources, relatively low earnings of primary care practitioners compared to specialists, low priority of primary care in medical education and training, lack of formal guidelines for information transfer between primary care practitioners and specialists and disregard of clinical routine data in the context of medical service planning. Compared to results of an earlier assessment in Switzerland, an improvement of seven indicators could be stated since 1995. As a

Matyáš, Robert; Šelešovský, Jakub; Musil, Tomáš

2012-04-30

The sensitivity to friction for a selection of primary explosives has been studied using a small BAM friction apparatus. The probit analysis was used for the construction of a sensitivity curve for each primary explosive tested. Two groups of primary explosives were chosen for measurement (a) the most commonly used industrially produced primary explosives (e.g. lead azide, tetrazene, dinol, lead styphnate) and (b) the most produced improvised primary explosives (e.g. triacetone triperoxide, hexamethylenetriperoxide diamine, mercury fulminate, acetylides of heavy metals). A knowledge of friction sensitivity is very important for determining manipulation safety for primary explosives. All the primary explosives tested were carefully characterised (synthesis procedure, shape and size of crystals). The sensitivity curves obtained represent a unique set of data, which cannot be found anywhere else in the available literature. Copyright © 2012 Elsevier B.V. All rights reserved.

Full Text Available Mycosis fungoides (MF is the most frequent type of primary cutaneous T-cell/NK-cell lymphoma. The Koebner phenomenon is defined as the appearance of cutaneous lesions on previously noninvolved skin following trauma and is observed in a series of cutaneous diseases including psoriasis, lichen planus, viral warts, molluscum contagiosum, etc. In this case report, 3 patients with longstanding MF are presented, the 1st with the appearance of a circumscribed early-stage type MF lesion rapidly following a surgical excision of an infundibular cyst, the 2nd with the appearance of a unique unilateral palmar tumoral MF lesion at the pressure site of a crutch, and the 3rd presented localized MF early stage lesions at the friction site of a belt. This report suggests that some MF patients may experience Koebner phenomenon-induced MF lesions and that MF should be added to the long list of skin diseases potentially exhibiting the Koebner phenomenon.

Multiple neoplasms, single primaries, and patient survival

2014-01-01

Multiple primary neoplasms in surviving cancer patients are relatively common, with an increasing incidence. Their impact on survival has not been clearly defined. This was a retrospective review of clinical data for all consecutive patients with histologically confirmed cancer, with emphasis on single versus multiple primary neoplasms. Second primaries discovered at the workup of the index (first) primary were termed simultaneous, if discovered within 6 months of the index primary were called synchronous, and if discovered after 6 months were termed metachronous. Between 2005 and 2012, of 1,873 cancer patients, 322 developed second malignancies; these included two primaries (n=284), and three or more primaries (n=38). Forty-seven patients had synchronous primaries and 275 had metachronous primaries. Patients with multiple primaries were predominantly of Caucasian ancestry (91.0%), with a tendency to develop thrombosis (20.2%), had a strong family history of similar cancer (22.3%), and usually presented with earlier stage 0 through stage II disease (78.9%). When compared with 1,551 patients with a single primary, these figures were 8.9%, 15.6%, 18.3%, and 50.9%, respectively (P≤0.001). Five-year survival rates were higher for metachronous cancers (95%) than for synchronous primaries (59%) and single primaries (59%). The worst survival rate was for simultaneous concomitant multiple primaries, being a median of 1.9 years. The best survival was for patients with three or more primaries (median 10.9 years) and was similar to the expected survival for the age-matched and sex-matched general population (P=0.06991). Patients with multiple primaries are usually of Caucasian ancestry, have less aggressive malignancies, present at earlier stages, frequently have a strong family history of similar cancer, and their cancers tend to have indolent clinical behavior with longer survival rates, possibly related to genetic predisposition

Innervated boomerang flap for finger pulp reconstruction.

Chen, Shao-Liang; Chiou, Tai-Fung

2007-11-01

The boomerang flap originates from the dorsolateral aspect of the proximal phalanx of an adjacent digit and is supplied by the retrograde blood flow through the vascular arcades between the dorsal and palmar digital arteries. To provide sensation of the boomerang flap for finger pulp reconstruction, the dorsal sensory branch of the proper digital nerve and the superficial sensory branch of the corresponding radial or ulnar nerve are included within the skin flap. After transfer of the flap to the injured site, epineural neurorrhaphies are done between the digital nerves of the pulp and the sensory branches of the flap. We used this sensory flap in five patients, with more than 1 year follow-up, and all patients achieved measurable two-points discrimination. The boomerang flap not only preserves the proper palmar digital artery but also provides an extended and innervated skin paddle. It seems to be an alternative choice for one-stage reconstruction of major pulp defect.

Full Text Available India is undergoing a rapid transformation in terms of governance, administrative reforms, newer policy develoment, and social movements. India is also considered one of the most vibrant economies in the world. The current discourse in public space is dominated by issues such as economic development, security, corruption free governance, gender equity, and women safety. Healthcare though remains a pressing need of population; seems to have taken a backseat. In the era of decreasing subsidies and cautious investment in social sectors, the 2 nd National Conference on Family Medicine and Primary Care 2015 (FMPC brought a focus on "healthcare" in India. The theme of this conference was "Healthcare is Primary." The conference participants discussed on the theme of why healthcare should be a national priority and why strong primary care should remain at the center of healthcare delivery system. The experts recommended that India needs to strengthen the "general health system" instead of focusing on disease based vertical programs. Public health system should have capacity and skill pool to be able to deliver person centered comprehensive health services to the community. Proactive implementation of policies towards human resource in health is the need of the hour. As the draft National Health Policy 2015 is being debated, "family medicine" (academic primary care, the unfinished agenda of National Health Policy 2002, remains a priority area of implementation.

Self-measurement of blood pressure (BP) might offer some advantages in diagnosis and therapeutic evaluation and in patient management of hypertension. Recently, wrist-cuff devices for self-measurement of BP have gained more than one-third of the world market share. In the present study, we validated wrist-cuff devices and compared the results between wrist- and arm-cuff devices. The factors affecting the accuracy of wrist-cuff devices were also studied. The research group to assess the validity of automated blood pressure measuring device consisted of 13 institutes in Japan, which validated two wrist-cuff devices (WC-1 and WC-2) and two arm-cuff devices (AC-1 and AC-2). They used a crossover method, where the comparison was done between auscultation, by two observers by means of a double stethoscope on one arm and the device on the opposite arm or wrist. There was good inter-observer agreement for the auscultation method in each institute (systolic blood pressure (SBP), -0.1 +/- 2.8 mmHg; diastolic blood pressure (DBP), -0.1 +/- 2.6 mmHg, n = 498). The mean difference between auscultation and the device was minimal both in arm-cuff devices (mean difference for AC-1, 2.2/1.9 mmHg, n = 97 and for AC-2, 5.1/2.9 mmHg, n = 136, SBP/DBP) and wrist-cuff devices (mean difference for WC-1, -2.1/1.2 mmHg, n = 173 mmHg and for WC-2, -2.3/-5.6 mmHg, n = 92). The standard deviation of the difference (SDD) in wrist-cuff devices, however (SDD for WC-1, 9.7/7.3 mmHg and for WC-2, 10.2/8.6 mmHg), was larger than that of the arm-cuff devices (SDD for AC-1, 5.6/6.6 mmHg and for AC-2, 6.3/5.1 mmHg). Grading of AC-1 and AC-2 based on criteria of British Hypertension Society was A/A and B/A, respectively, while that of WC-1 and WC-2 was C/B and D/B, respectively. Using the same validation protocol, the results of validation for one device were divergent in each institute. In wrist-cuff devices, the BP value obtained in palmar flexion was significantly higher and that obtained in palmar

Normocalcemic primary hyperparathyroidism

Bilezikian, John P.; Silverberg, Shonni J.

2011-01-01

SUMMARY Primary hyperparathyroidism is a common disorder of mineral metabolism characterized by incompletely regulated, excessive secretion of parathyroid hormone from one or more of the parathyroid glands. The historical view of this disease describes two distinct entities marked by two eras. When primary hyperparathyroidism was first discovered about 80 years ago, it was always symptomatic with kidney stones, bone disease and marked hypercalcemia. With the advent of the multichannel autoanalyzer about 40 years ago, the clinical phenotype changed to a disorder characterized by mild hypercalcemia and the absence of classical other features of the disease. We may now be entering a 3rd era in the history of this disease in which patients are being discovered with normal total and ionized serum calcium concentrations but with parathyroid hormone levels that are consistently elevated. In this article, we describe this new entity, normocalcemic primary hyperparathyroidism, a forme fruste of the disease. PMID:20485897

Full Text Available Catatonia is a syndrome characterized by mutism, immobility, negativism, stereotypy, mannerisms, echophenomena, perseveration and passive obedience. The underlying causes can be psychiatric or may be associated with general medical status or neurological diseases. Additionally catatonia has two subtypes as malignant and nonmalignant catatonia. Main symptoms of malignant catatonia are hyperthermia and autonomic symptoms such as tachycardia, tachypnea and hyperhidrosis. It is important to make the diagnosis as early as possible for an appropriate medical treatment. Clinicians should be aware of the fatal outcome of the disease.

Highlights: ► The friction sensitivity of 14 samples of primary explosives was determined. ► The same apparatus (small scale BAM) and the same method (probit analysis) was used. ► The crystal shapes and sizes were documented with microscopy. ► Almost all samples are less sensitive than lead azide, which is commercially used. ► The organic peroxides (TATP, DADP, HMTD) are not as sensitive as often reported. - Abstract: The sensitivity to friction for a selection of primary explosives has been studied using a small BAM friction apparatus. The probit analysis was used for the construction of a sensitivity curve for each primary explosive tested. Two groups of primary explosives were chosen for measurement (a) the most commonly used industrially produced primary explosives (e.g. lead azide, tetrazene, dinol, lead styphnate) and (b) the most produced improvised primary explosives (e.g. triacetone triperoxide, hexamethylenetriperoxide diamine, mercury fulminate, acetylides of heavy metals). A knowledge of friction sensitivity is very important for determining manipulation safety for primary explosives. All the primary explosives tested were carefully characterised (synthesis procedure, shape and size of crystals). The sensitivity curves obtained represent a unique set of data, which cannot be found anywhere else in the available literature.

[Primary care in Ireland].

Science.gov (United States)

Sánchez-Sagrado, T

Spanish doctors are still leaving the country to look for quality work. Ireland is not a country with many Spanish professionals but it is interesting to know its particular Health care system. Ireland is one of the countries with a national health care system, although it has a mixture of private health care insurance schemes. People have a right to health care if they have been living in Ireland at least for a year. Access to the primary care health system depends on age and income: free of charge for Category 1 and co-payments for the rest. This division generates great inequalities among the population. Primary Care doctors are self-employed, and they work independently. However, since 2001 they have tended to work in multidisciplinary teams in order to strengthen the Primary Care practice. Salary is gained from a combination of public and private incomes which are not differentiated. The role of the General Practitioner consists in the treatment of acute and chronic diseases, minor surgery, child care, etc. There is no coordination between Primary and Secondary care. Access to specialised medicine is regulated by the price of consultation. Primary Care doctors are not gatekeepers. To be able to work here, doctors must have three years of training after medical school. After that, Continuing Medical Education is compulsory, and the college of general practitioners monitors it annually. The Irish health care system does not fit into the European model. Lack of a clear separation between public and private health care generates great inequalities. The non-existence of coordination between primary and specialised care leads to inefficiencies, which Ireland cannot allow itself after a decade of economic crisis.

Henderson, Julie; Javanparast, Sara; MacKean, Tamara; Freeman, Toby; Baum, Fran; Ziersch, Anna

2018-01-01

This paper reports findings from 55 stakeholder interviews undertaken in six Primary Health Networks (PHNs) in Australia as part of a study of the impact of population health planning in regional primary health organisations on service access and equity. Primary healthcare planning is currently undertaken by PHNs which were established in 2015 as commissioning organisations. This was a departure from the role of Medicare Locals, the previous regional primary health organisations which frequently provided services. This paper addresses perceptions of 23 senior staff, 11 board members and 21 members of clinical and community advisory councils or health priority groups from six case study PHNs on the impact of commissioning on equity. Participants view the collection of population health data as facilitating service access through redistributing services on the basis of need and through bringing objectivity to decision-making about services. Conversely, participants question the impact of the political and geographical context and population profile on capacity to improve service access and equity through service commissioning. Service delivery was seen as fragmented, the model is at odds with the manner in which Aboriginal Community Controlled Health Organisations (ACCHOs) operate and rural regions lack services to commission. As a consequence, reliance upon commissioning of services may not be appropriate for the Australian primary healthcare context. © 2017 John Wiley & Sons Ltd.

Full Text Available Background: Migration is an essential component of breast cancer metastasis, which studyhas been concentrated on culture of established breast cancer cell lines that do not accuratelyrepresent the sophistication and heterogeneity of patient's breast cancer. An attempt toperform migration assay using Boyden Chamber Assay (BCA on primary culture originatingfrom patient's breast cancer tissue was developed to accommodate upcoming study of breastcancer migration in lndonesian patients.Methods: Pathologically proven primary breast cancer tissue samples were obtained fromCiptomangunkusumo Hospital during core (n=4 and incisional (n=3 biopsies of stage llAup to stage lllA breast cancer patients. Following biopsy, the breast cancer tissue samplesunderwent processings to isolate the cancer cells. These cancer cells were -then resuspendedwithin Dulbecco's modified Eagle's medium (DMEM ahd cultured in 12-well plate. The growthof primary culture were observed and compared between the core biopsy and the incisionalbiopsy specimens. Optimization of BCA method was later performed to investigate themigration of the breast cancer primary culture towards different experirnental conditions, whichwere control, Fetal Bovine Serum (FBS, and Stromal Derived Factor-l (SDF-1. Two differentnumber of breast cancer cells were tested for the optimization of the BCA, which were 1 x 105and3x105cells.Results: None of the culture performed on core biopsy specimens grew, while one out ofthree incisional biopsy specimens grew until confluence. The one primary culture that grewwas later assesed using BCA to assess its migration index towards different experimentalconditions. Using 1 x 10s breast cancer cells in the BCA , the result of the absorbance level ofmigrated cells showed that the migration towards SDF-1 (0.529 nearly doubled the migrationtowards controlmedium (0.239 and FBS (0.209.

Objective To compare the effect of two different hand exercises on hand strength and vascular maturation in patients who underwent arteriovenous fistula surgery. Methods We recruited 18 patients who had chronic kidney disease and had undergone arteriovenous fistula surgery for hemodialysis. After the surgery, 10 subjects performed hand-squeezing exercise with GD Grip, and other 8 subjects used Soft Ball. The subjects continued the exercises for 4 weeks. The hand grip strength, pinch strength (tip, palmar and lateral pinch), and forearm circumference of the subjects were assessed before and after the hand-squeezing exercise. The cephalic vein size, blood flow velocity and volume were also measured by ultrasonography in the operated limb. Results All of the 3 types of pinch strengths, grip strength, and forearm circumference were significantly increased in the group using GD Grip. Cephalic vein size and blood flow volume were also significantly increased. However, blood flow velocity showed no difference after the exercise. The group using Soft Ball showed a significant increase in the tip and lateral pinch strength and forearm circumference. The cephalic vein size and blood flow volume were also significantly increased. On comparing the effect of the two different hand exercises, hand-squeezing exercise with GD Grip had a significantly better effect on the tip and palmar pinch strength than hand-squeezing exercise with Soft Ball. The effect on cephalic vein size was not significantly different between the two groups. Conclusion The results showed that hand squeezing exercise with GD Grip was more effective in increasing the tip and palmar pinch strength compared to hand squeezing exercise with soft ball.

2013-01-01

Full Text Available Background: Oral squamous cell carcinoma (SCC is one name that causes panic and holds an undeserved high ranking as a killer. Another important condition which has become a major public health issue in South East Asia is oral submucous fibrosis (OSF. Not all the people using tobacco suffer from these diseases. Genetic predisposition might explain such an individual variability that can be predicted by using various cytogenetic markers. However, these studies are far more costly and complicated. So, dermatoglyphics may be of immense clinical significance to segregate those individuals who are at an increased risk for developing these diseases. Aim: The present study was conducted to analyze the palmar dermatoglyphics in SCC and OSF and find a "dermatoglyphic marker", if any. Study Design: Cross sectional study. Materials and Methods: 120 individuals were divided into four groups based upon their habits of tobacco/areca nut usage and presence of OSF/SCC. Dermatoglyphic patterns were recorded using standard ink method. Various patterns were analysed statistically in the four groups. Results and Conclusion: In SCC, there was an increase in frequency of arch and ulnar loop patterns on fingertips, decrease in frequency of simple whorl patterns on fingertips, decrease in frequency of palmar accessory triradii on right and left hands. Significant findings in OSF included an increase in frequency of arch and ulnar loop pattern, decrease in frequency of simple whorl patterns on fingertips, decrease in atd angle on right hand, decrease in frequency of palmar accessory triradii on right hand. The results revealed that the field of dermatoglyphics holds promising results for determining the genetic susceptibility of individuals to develop SCC and OSF.

Full Text Available Primary sclerosing cholangitis is a progressive disease, and coincidentally in pregnancy it is rare. It is characterized by progressive inflammation and destruction of bile ducts finally resulting in liver failure. A rare case of primary sclerosing cholangitis in pregnancy is presented. The course of the pregnancy was marked by threatened preterm delivery and exacerbation of cholestasis. She was successfully treated with ursodeoxycholic acid (UDCA. Although, primary sclerosing cholangitis has both maternal and fetal effects on pregnancy, the overall outcome is favorable. Only few cases have been reported using high dose ursodeoxycholic acid for primary sclerosing cholangitis in pregnancy, it often improves pruritus but has no protection against stillbirth. Data on the safety to the fetus or neonate and long-term outcome are scarce.

Are chiropractors in the uk primary healthcare or primary contact practitioners?: a mixed methods study

Directory of Open Access Journals (Sweden)

Jones-Harris Amanda R

2010-10-01

Full Text Available Abstract Background One of the debates regarding the role of chiropractors is whether or not they should be considered as primary healthcare practitioners. Primary care is often used to describe chiropractic but without any definition of what is meant by the term. Primary healthcare itself has many definitions and this adds to the problem. Existing research literature, based mostly in the USA, suggests that the use of the title "primary healthcare professional" by chiropractors is central to the identity of the profession. It has also been suggested that the concept of primary care is misused by chiropractors because they have not examined the concept in detail and thus do not understand it. For the sake of quality of patient care and for the legitimacy of the profession, chiropractors in the UK need to agree on their healthcare role. This study aimed to examine the opinions of chiropractors towards the use of the term primary healthcare when applied to chiropractic practice within the UK. Methods A sequential study of exploratory design was used; this model is characterised by an initial phase of qualitative data collection and analysis that precedes and informs the quantitative phase of data collection and analysis. In this study, interviews with members of chiropractic teaching faculty were used to inform the development of a questionnaire used to survey the opinions of chiropractors in the UK. Results There was a general consensus of opinion that chiropractors are primary contact practitioners, who work in a primary healthcare setting and that to be able to fulfil this healthcare role, chiropractors must be able to diagnose patients and refer when required. Participants did not feel that chiropractors are able to treat all of the most common medical conditions that present in a primary healthcare setting. Conclusions The findings of this study suggest that chiropractors in the UK view their role as one of a primary contact healthcare

Gerber, Robert A; Perry, Richard; Thompson, Robin; Bainbridge, Christopher

2011-04-12

Dupuytren's disease is a fibro-proliferative disorder affecting ~3-5% of the UK population. Current surgical treatments for Dupuytren's contracture (DC) include fasciectomy and fasciotomy. We assessed the clinical management of DC in England over a 5-year period; associated NHS costs were assessed for a 1-year period. Hospital Episode Statistics were extracted from April 2003 to March 2008 for patients with Palmar Fascial Fibromatosis (ICD10=M720) and DC-related procedures. Variables included demographics, OPCS, patient status and physician specialty. To estimate 2010-2011 costs, HRG4 codes and the National Schedule of Tariff 2010-11-NHS Trusts were applied to the 2007-2008 period. Over 5 years, 75,157 DC admissions were recorded; 64,506 were analyzed. Mean admissions per year were 12,901 and stable. Day cases increased from 42% (2003-2004) to 62% (2007-2008). The percent of patients having two or more admissions per year increased from 5.5% in 2003-2004 to 26.1% in 2007-2008. Between 2003 and 2007, 91% of procedures were Fasciectomy. Revision of Fasciectomy and Fasciotomy each accounted for ~4%; Amputation for 1%. In 2007, classification was extended to identify Digital Fasciectomy, its Revision and Dermofasciectomy. In 2007-2008, admissions were: 70% Palmar Fasciectomy, 16% Digital Fasciectomy, 1.3% Other Fasciectomy, 4.4% Revision of Palmar Fasciectomy, 1.3% Revision of Digital Fasciectomy, 3.8% Division of Palmar Fascia, 2.6% Dermofasciectomy and 1.1% Amputation. 79% of cases were overseen by trauma and orthopaedic surgeons, 19% by plastic surgeons. Mean (±SD) inpatient hospital length of stay was 1.5 (±1.4) days in 2003-2004 and 1.0 (±1.3) days in 2007-2008. Total estimated costs for 1 year (2010-2011) were £41,576,141. Per-patient costs were £2,885 (day case) and £3,534 (inpatient). Costs ranged from £2,736 (day-case Fasciectomy) to £9,210 (day-case Revision Digital). Between 2003 and 2008, fasciectomy was the most common surgical procedure for DC in

To study the operative procedure and the effectiveness of arthroscopic therapy for ankle joint impingement syndrome after operation of ankle joint fracture dislocation. Between March 2008 and April 2010, 38 patients with ankle joint impingement syndrome after operation of ankle joint fracture dislocation were treated. Among them, there were 28 males and 10 females with an average age of 28 years (range, 18 to 42 years). The time from internal fixation to admission was 12-16 months (mean, 13.8 months). There were pressing pain in anterolateral and anterior ankle. The dorsal extension ranged from -20 to -5 degrees (mean, -10.6 degrees), and the palmar flexion was 30-40 degrees (mean, 35.5 degrees). The total score was 48.32 +/- 9.24 and the pain score was 7.26 +/- 1.22 before operation according to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score system. The X-ray films showed osteophyte formation in anterior tibia and talus; MRI showed cartilage injury in 22 cases. Arthroscopic intervention included removing osteophytes, debriding fabric scars and synovial membrane tissues, and removing osteochondral fragments. Arthroscopic microfracture technique was used in 22 patients with cartilage injury. All incisions healed primarily. Thirty-eight cases were followed up 10-26 months (mean, 16 months). At last follow-up, 26 patients had normal range of motion (ROM); the dorsal extension was 15-25 degrees (mean, 19.6 degrees) and the palmar flexion was 35-45 degrees (mean, 40.7 degrees). Eight patients had mild limited ROM; the dorsal extension was 5-15 degrees (mean, 7.2 degrees) and the palmar flexion was 35-45 degrees (mean, 39.5 degrees). Four patients had mild limited ROM and pain in posterior portion of the ankle after a long walking (3-4 hours); the dorsal extension was 0-5 degrees (mean, 2.6 degrees) and the palmar flexion was 35-40 degrees (mean, 37.5 degrees). The total score was 89.45 +/- 9.55 and the pain score was 1.42 +/- 1.26 after

Full Text Available Primary Renal Sarcoma is rare tumor comprising only 1% of all renal tumours. Synovial sarcomas are generally deep-seated tumors arising in the proximity of large joints of adolescents and young adults and account for 5-10% of all soft tissue tumours. Primary synovial sarcoma of kidney is rare and has poor prognosis. It can only be diagnosed by immunohistochemistry. It should be considered as a differential in sarcomatoid and spindle cell tumours. We present a case of 33-year-old female, who underwent left sided radical nephrectomy for renal tumour. Histopathology and genetic analysis diagnosed it to be primary renal synovial sarcoma. Patient underwent radiation therapy and 2 years follow up is uneventful. A brief case report with review of literature is presented.

Structures in the energy spectrum of primary cosmic rays at the 'knee' region and for energies higher than 1 EeV are obtained through studying extensive air showers (EAS). The main problem of the research is the fact that we work in the ranges of highly fluctuating parameters used to obtain the primary energy spectrum. In this paper the log-normal distribution for the error function has been used in convolution with the power spectrum to explain the Yakutsk experimental data. Similar results have been obtained for the gamma distribution as the error function. Using the power law primary spectrum in the energy region around 10 19 eV we will argue that the primary Yakutsk spectrum is overestimated. In the best case this overestimation is not less than 42%.

Full Text Available Context: Immunization, a well-known and effective method of preventing childhood illnesses is basic service under primary health care. Most surveys in India measure primary immunization coverage and quality, but no "Gender Equality." Aims: Assess "Gender Equality" in primary immunization with reference to coverage, quality, and place of immunization. Settings and Design: Cross-sectional survey in a primary health center, Pune, Maharashtra using World Health Organization 30-cluster sampling method with 14 beneficiaries (7 girls and 7 boys to be selected from each cluster. Instead of 420 children, data collected for 345 children, as requisite numbers of children were not available in low population villages and also children whose mothers were not present during survey were excluded. Materials and Methods: Vaccination data collected from either records and/or history by mother. Children born on or between 13-09-2009 and 13-09-2010, were included. Statistical Analysis Used: SPSS 14.01 version with Chi-square as test of significance. Results: Of the study population, 171 (49.6% were females and 174 (50.4% males. A total of 64.1% children had immunization records with female proportion 69.0% and males 59.2%. Primary immunization coverage was 80.0%, with female proportion 82.5% and males 77.6%. One male child was completely unimmunized and remaining partially immunized, with unaware of schedule and illness of child being major reasons for partial immunization. There was no gender wise statistically significant difference observed in Primary Immunization with reference to coverage, quality, and place of immunization. Conclusions: Immunization coverage is nearing 85% benchmark with major contribution from Universal Immunization Program. Gender Equality observed in primary immunization. Preservation of immunization records by community and timely vaccinations are areas for improvement.

Primary optic nerve sheath meningioma

Energy Technology Data Exchange (ETDEWEB)

Jeremic, Branislav [International Atomic Energy Agency, Vienna (Austria); Pitz, Susanne (eds.) [University Eye Hospital, Mainz (Germany)

2008-07-01

Optic nerve sheath meningioma (ONSM) is a rare tumour. Cases are usually separated into primary ONSM, which arises either intraorbitally or, less commonly, intracanalicularly, and secondary ONSM, which arises intracranially and subsequently invades the optic canal and orbit. This is the first book to cover all important aspects of the diagnosis and treatment of primary ONSM. After a general introduction, individual chapters discuss the clinical presentation, clinical examination and diagnosis, imaging, and histology. Treatment options are then addressed in detail, with special emphasis on external beam radiation therapy, and in particular stereotactic fractionated radiation therapy. The latter has recently produced consistently good results and is now considered the emerging treatment of choice for the vast majority of patients with primary ONSM. This well-illustrated book will prove invaluable to all practitioners who encounter primary ONSM in their clinical work. (orig.)

Primary health services at district level in South Africa: a critique of the primary health care approach

Directory of Open Access Journals (Sweden)

Dookie Sunitha

2012-07-01

Full Text Available Abstract Background The rhetoric of primary health care philosophy in the district health system is widely cited as a fundamental component of the health transformation process in post-apartheid South Africa. Despite South Africa’s progress and attempts at implementing primary health care, various factors still limit its success. Discussion Inconsistencies and poor understanding of primary care and primary health care raises unrealistic expectations in service delivery and health outcomes, and blame is apportioned when expectations are not met. It is important for all health practitioners to consider the contextual influences on health and ill-health and to recognise the role of the underlying determinants of ill-health, namely, social, economic and environmental influences. The primary health care approach provides a strong framework for this delivery but it is not widely applied. There is a need for renewed political and policy commitments toward quality primary health care delivery, re-orientation of health care workers, integration of primary health care activities into other community-based development, improved management skills and effective coordination at all levels of the health system. There should also be optimal capacity building, and skills development in problem-solving, communication, networking and community participation. Summary A well-functioning district health system is required for the re-engineering of primary health care. This strategy requires a strong leadership, a strengthening of the current district heath system and a greater emphasis on health promotion, prevention, and community participation and empowerment.

Puberty is a defining time of many adolescents' lives. It is a series of events that includes thelarche, pubarche, and menarche. Primary amenorrhea is the absence of menarche. There are numerous etiologies including outflow tract obstructions, gonadal dysgenesis, and anomalies of the hypothalamic axis. This review's aims are to define primary amenorrhea and describe the various causes, their workups, associated comorbidities, and treatment options. At the end, a generalist should be able to perform an assessment of an adolescent who presents with primary amenorrhea and, if warranted, begin initial treatment.

20 cases of primary benign and malignant bone tumours in children were reported. The most common tumours were Ewing's sarcoma, aneurismal bone cyst, benign osteoblastoma and osteoid osteoma. Some rare primary bone tumours in children (osteochondroma, chondroblastoma 6F, primary lymphoma of bone and neurofibromatosis with unusual cervical spinal changes) were also reported. The authors believe that radiographic findings together with clinical history and clinical examination may yield a high percentage of accurate diagnoses. Although microscopy is essential in the final diagnosis, the microscopic report should be also accepted with caution.

The long term importance of English primary care groups for integration in primary health care and deinstitutionalisation of hospital care.

Goodwin, N

2001-01-01

This article reviews the impact of successive experiments in the development of primary care organisations in England and assesses the long-term importance of English primary care groups for the integration of health and community and health and social care and the deinstitutionalisation of hospital care. Governments in a number of Western countries are attempting to improve the efficiency, appropriateness and equity of their health systems. One of the main ways of doing this is to devolve provision and commissioning responsibility from national and regional organisations to more local agencies based in primary care. Such primary care organisations are allocated budgets that span both primary and secondary (hospital) services and also, potentially, social care. This article is based on a systematic review of the literature forthcoming from the UK Government's Department of Health-funded evaluations of successive primary care organisational developments. These include total purchasing pilots, GP commissioning group pilots, personal medical services pilots and primary care groups and trusts. Primary care organisations in England have proved to be a catalyst in facilitating the development of integrated care working between primary and community health services. Conversely, primary care organisations have proved less effective in promoting integration between health and social care agencies where most progress has been made at the strategic commissioning level. The development of primary care trusts in England is heralding an end to traditional community hospitals. The development of primary care groups in England are but an intermediate step of a policy progression towards future primary care-based organisations that will functionally integrate primary and community health services with local authority services under a single management umbrella.

Primary uterine inertia in four labrador bitches.

Science.gov (United States)

Davidson, Autumn P

2011-01-01

Uterine inertia is a common cause of dystocia in the bitch and is designated as primary (i.e., uterine contractions fail to ever be initiated) or secondary (i.e., uterine contractions cease after a period of time but before labor is completed). The etiology of primary uterine inertia is not well understood. The accurate diagnosis of primary uterine inertia requires the use of tocodynamometry (uterine monitoring). Primary uterine inertia has been postulated to result from a failure of luteolysis resulting in persistently elevated progesterone concentrations. In this study, primary uterine inertia was diagnosed in a series of four bitches in which luteolysis was documented suggesting some other etiopathogenesis for primary uterine inertia.

Explaining the de-prioritization of primary prevention: Physicians' perceptions of their role in the delivery of primary care

Kuo Christina L

2003-05-01

Full Text Available Abstract Background While physicians are key to primary preventive care, their delivery rate is sub-optimal. Assessment of physician beliefs is integral to understanding current behavior and the conceptualization of strategies to increase delivery. Methods A focus group with regional primary care physician (PCP Opinion Leaders was conducted as a formative step towards regional assessment of attitudes and barriers regarding preventive care delivery in primary care. Following the PRECEDE-PROCEED model, the focus group aim was to identify conceptual themes that characterize PCP beliefs and practices regarding preventive care. Seven male and five female PCPs (family medicine, internal medicine participated in the audiotaped discussion of their perceptions and behaviors in delivery of primary preventive care. The transcribed audiotape was qualitatively analyzed using grounded theory methodology. Results The PCPs' own perceived role in daily practice was a significant barrier to primary preventive care. The prevailing PCP model was the "one-stop-shop" physician who could provide anything from primary to tertiary care, but whose provision was dominated by the delivery of immediate diagnoses and treatments, namely secondary care. Conclusions The secondary-tertiary prevention PCP model sustained the expectation of immediacy of corrective action, cure, and satisfaction sought by patients and physicians alike, and, thereby, de-prioritized primary prevention in practice. Multiple barriers beyond the immediate control of PCP must be surmounted for the full integration of primary prevention in primary care practice. However, independent of other barriers, physician cognitive value of primary prevention in practice, a base mediator of physician behavior, will need to be increased to frame the likelihood of such integration.

Primary epididymal leiomyosarcoma occurs usually in older patients. We report a young patient of 35 years presenting with leiomyosarcoma of left epididymis. He did not have any metastasis and underwent left high inguinal orchiectomy. He is on regular follow-up and disease free for last two years.

Integrated primary health care in Australia

Gawaine Powell Davies

2009-10-01

Full Text Available Introduction: To fulfil its role of coordinating health care, primary health care needs to be well integrated, internally and with other health and related services. In Australia, primary health care services are divided between public and private sectors, are responsible to different levels of government and work under a variety of funding arrangements, with no overarching policy to provide a common frame of reference for their activities. Description of policy: Over the past decade, coordination of service provision has been improved by changes to the funding of private medical and allied health services for chronic conditions, by the development in some states of voluntary networks of services and by local initiatives, although these have had little impact on coordination of planning. Integrated primary health care centres are being established nationally and in some states, but these are too recent for their impact to be assessed. Reforms being considered by the federal government include bringing primary health care under one level of government with a national primary health care policy, establishing regional organisations to coordinate health planning, trialling voluntary registration of patients with general practices and reforming funding systems. If adopted, these could greatly improve integration within primary health care. Discussion: Careful change management and realistic expectations will be needed. Also other challenges remain, in particular the need for developing a more population and community oriented primary health care.

Surgery remains the mainstay of melanoma therapy, regardless of the tumor site. Only the early diagnosis combined with proper surgical therapy currently gives patients affected by this malignancy the chance for a full cure. The main goal of surgical therapy is to provide the local control of the disease and to secure long-term survival of the patient without reasonable functional and esthetic impairment. The recommended method of biopsy—excisional biopsy, as an initial diagnostic and, to some extent, therapeutic procedure—is performed under local anesthesia as an elliptical incision with visual clear margins of 1–3 mm and with some mm of subcutaneous tissue. The extent of radical excision of the primary tumor (or scar after excisional biopsy) is based on the histopathologic characteristics of the primary tumor and usually consists of 1–2 cm margins with primary closure. The philosophy behind conducted randomized clinical trials has been to find the most conservative surgical approach that is able to guarantee the same results as more demolitive treatment. This has been the background of the trials designed to define the correct margins of excision around a primary cutaneous melanoma. Much less definition can be dedicated to the surgical management of patients with non-cutaneous melanomas.

There is emerging evidence that strong primary care achieves better health at lower costs. Although primary care can be measured, in many countries, including Austria, there is little understanding of primary care development. Assessing the primary care development in Austria. A primary care assessment tool developed by Barbara Starfield in 1998 was implemented in Austria. This tool defines 15 primary care characteristics and distinguishes between system and practice characteristics. Each characteristic was evaluated by six Austrian primary care experts and rated as 2 (high), 1 (intermediate) or 0 (low) points, respectively, to their primary care strength (maximum score: n = 30). Austria received 7 out of 30 points; no characteristic was rated as '2' but 8 were rated as '0'. Compared with the 13 previously assessed countries, Austria ranks 10th of 14 countries and is classified as a 'low primary care' country. This study provides the first evidence concerning primary care in Austria, benchmarking it as weak and in need of development. The practicable application of an existing assessment tool can be encouraging for other countries to generate evidence about their primary care system as well.

After the first cases of primary aldosteronism were described and characterized by Conn, a substantial body of experimental and clinical evidence about the long-term effects of excess aldosterone on the cardiovascular system was gathered over the last 5 decades. The prevalence of primary aldosteronism varies considerably between different studies among hypertensive patients, depending on patient selection, the used diagnostic methods, and the severity of hypertension. Prevalence rates vary from 4.6 to 16.6% in those studies in which confirmatory tests to diagnose primary aldosteronism were used. There is also growing evidence indicating that prolonged exposure to elevated aldosterone concentrations is associated with target organ damage in the heart, kidney, and arterial wall, and high cardiovascular risk in patients with primary aldosteronism. Therefore, the aim of treatment should not be confined to BP normalization and hypokalemia correction, but rather should focus on restoring the deleterious effects of excess aldosterone on the cardiovascular system. Current evidence convincingly demonstrates that both surgical and medical treatment strategies beneficially affect cardiovascular outcomes and mortality in the long term. Further studies can be expected to provide better insight into the relationship between cardiovascular risk and complications and the genetic background of primary aldosteronism. © Georg Thieme Verlag KG Stuttgart · New York.

Monitoring quality in Israeli primary care: The primary care physicians' perspective

Directory of Open Access Journals (Sweden)

Nissanholtz-Gannot Rachel

2012-06-01

Full Text Available Abstract Background Since 2000, Israel has had a national program for ongoing monitoring of the quality of the primary care services provided by the country's four competing non-profit health plans. Previous research has demonstrated that quality of care has improved substantially since the program's inception and that the program enjoys wide support among health plan managers. However, prior to this study there were anecdotal and journalistic reports of opposition to the program among primary care physicians engaged in direct service delivery; these raised serious questions about the extent of support among physicians nationally. Goals To assess how Israeli primary care physicians experience and rate health plan efforts to track and improve the quality of care. Method The study population consisted of primary care physicians employed by the health plans who have responsibility for the quality of care of a panel of adult patients. The study team randomly sampled 250 primary-care physicians from each of the four health plans. Of the 1,000 physicians sampled, 884 met the study criteria. Every physician could choose whether to participate in the survey by mail, e-mail, or telephone. The anonymous questionnaire was completed by 605 physicians – 69% of those eligible. The data were weighted to reflect differences in sampling and response rates across health plans. Main findings The vast majority of respondents (87% felt that the monitoring of quality was important and two-thirds (66% felt that the feedback and subsequent remedial interventions improved medical care to a great extent. Almost three-quarters (71% supported continuation of the program in an unqualified manner. The physicians with the most positive attitudes to the program were over age 44, independent contract physicians, and either board-certified in internal medicine or without any board-certification (i.e., residents or general practitioners. At the same time, support for the

To know the three questions about multiple primary cancers: 1) what are the characteristics of persons having multiple primary cancer? 2) Dose presence of a single primary concern after the susceptibility to multiple primary cancers? 3) Dose the location of one multiple primary cancer influence the site of others?, we analysed 121 cases of multiple primary malignant neoplasms registered in Seoul National University Hospital during 8years from July 1978 to August 1986. Of 121 cases, double primary malignant neoplasms were 119 cases and triple were 2 cases. The incidence of multiple primary malignant neoplasms was 0.7%. The metachronous tumor(> 6 months) was found in 70 cases and the median time between the first and the second was 32 months. The most commonly associated tumors were stomach and primary liver carcinoma. Cervix and Lung cancer, Stomach and Rectal cancer, Stomach and Esophagus cancer were also commonly associated

"Efforts to broaden students' aspirations, particularly in relation to STEM, need to begin in primary school." Kings College London "Aspires" Research Project 2013 From my outreach activity I have learnt that primary teachers could feel under pressure when faced with delivering the science curriculum. The teachers could be lacking confidence in their subject knowledge, lacking the equipment needed to deliver practical science or lacking enthusiasm for the subject. In addition, English and Mathematics were the subjects that were externally tested and reported to the authorities and so some teachers felt that time for science was being marginalised to ensure the best results in the externally assessed subjects. In my work with The Ogden Trust Primary Science team I have been involved in developing a range of strategies to address some of the issues outlined above. • CPD (Teacher Training) Programme We have provided free training to improve teachers knowledge and understanding of key physics concepts to GCSE standard and a practical workshop consisting of ten investigations, extension and challenge tasks. The teachers each receive a book of lesson plans and a resource box containing a class set of the equipment required. The four year programme covers Forces Light and Sound Electricity Earth & Space • "Phiz Labs" Funding from The Ogden Trust has allowed us to set up science laboratories within primary schools. The pupils have lab coats, goggles and access to a range of equipment that allows them to participate in more practical science activity and open-ended investigative work. My Phiz Lab is in the secondary school where I teach physics and practical workshops for primary pupils and teachers are held there on a regular basis. • Enrichment In order to enthuse and challenge the primary pupils a variety of enrichment activities take place. These include "Physics of Go-Karts" and "Particle Physics for Primary" workshops, competitions and regional Science Fairs

In October 2014, the National Center for Integrative Primary Healthcare (NCIPH) was launched as a collaboration between the University of Arizona Center for Integrative Medicine and the Academic Consortium for Integrative Health and Medicine and supported by a grant from the Health Resources and Services Administration. A primary goal of the NCIPH is to develop a core set of integrative healthcare (IH) competencies and educational programs that will span the interprofessional primary care training and practice spectra and ultimately become a required part of primary care education. This article reports on the first phase of the NCIPH effort, which focused on the development of a shared set of competencies in IH for primary care disciplines. The process of development, refinement, and adoption of 10 “meta-competencies” through a collaborative process involving a diverse interprofessional team is described. Team members represent nursing, the primary care medicine professions, pharmacy, public health, acupuncture, naturopathy, chiropractic, nutrition, and behavioral medicine. Examples of the discipline-specific sub-competencies being developed within each of the participating professions are provided, along with initial results of an assessment of potential barriers and facilitators of adoption within each discipline.

We report a case of intraorbital meningioma. Operative findings and histopathological examination revealed the tumoc to be meningothelial meningloma and to be located entirely outside the optic dura. This case demonstrates the occurrence of primary intraorbital ectopic meningioma, and the tumor was removed through a modified Dolenc approach. The primary intraorbital ectopic meningioma is discussed and the surgical approach to the orbital apex region is reviewed. ImagesFigure 1Figure 2Figure 4Figure 5 PMID:17171081

Primary headaches in children

Directory of Open Access Journals (Sweden)

Ajay Kumar Pan

2015-01-01

Full Text Available Headache is a widespread clinical problem; the prevalence is high in all age groups, from which children and teenagers are not spared. It has been reported that, as many as 75% of school-age children may experience headache infrequently, among them 10% have recurrent headaches. [1],[2] The vast majority of headaches are primary and classified as migraine, tension-type headache (TTH, cluster headache, and other trigeminal autonomic cephalgias. The type of primary headaches could usually be diagnosed by a thorough and careful history taking, and physical examination. Once the diagnosis of migraine is established and appropriate reassurance provided, a balanced and individually tailored treatment plan can be instituted. The goal of treatment includes abortive or acute pain treatment, preventive long-term treatment, and biobehavioral therapy. Knowledge of precise impact of primary headaches on child′s quality of life helps to design a proper comprehensive treatment plan.

Craniopharyngiomas are benign but aggressive epithelial tumors usually originating in the anterior lobe of the pituitary gland from squamous remnants of an incompletely involuted craniopharingeal duct developing from the Rathke pouch. To the authors' knowledge only 1 patient of a primary isolated ethmoidal craniopharyngioma has been reported in the literature.The authors report the case of a 17-year-old boy with a primary extracranial ethmoidal craniopharyngioma. An endoscopic endonasal approach was employed to resect the tumor. After 2 years of clinical and radiological follow-up no recurrence of disease was observed.Primary ethmoidal craniopharyngiomas are rare entities and biopsy is necessary for diagnosis. However, a preoperative assessment by means of nasal endoscopy, computed tomography scan, and enhanced magnetic resonance imaging is mandatory to better evaluate the extension and characteristics of the tumor. The endoscopic endonasal technique is a safe and effective approach for the treatment of these lesions.

In light of the increasing demand for primary care services and the changing scope of health care, it is important to consider how the principles of primary care are taught in medical school. While the majority of schools have increased students' exposure to primary care, they have not developed a standardized primary care curriculum for undergraduate medical education. In 2013, the authors convened a group of educators from primary care internal medicine, pediatrics, family medicine, and medicine-pediatrics, as well as five medical students to create a blueprint for a primary care curriculum that could be integrated into a longitudinal primary care experience spanning undergraduate medical education and delivered to all students regardless of their eventual career choice.The authors organized this blueprint into three domains: care management, specific areas of content expertise, and understanding the role of primary care in the health care system. Within each domain, they described specific curriculum content, including longitudinality, generalism, central responsibility for managing care, therapeutic alliance/communication, approach to acute and chronic care, wellness and prevention, mental and behavioral health, systems improvement, interprofessional training, and population health, as well as competencies that all medical students should attain by graduation.The proposed curriculum incorporates important core features of doctoring, which are often affirmed by all disciplines but owned by none. The authors argue that primary care educators are natural stewards of this curriculum content and can ensure that it complements and strengthens all aspects of undergraduate medical education.

To determine normal anatomy of extrinsic and intrinsic carpal ligaments at ultrasonography (US). In the first part of the study, two musculoskeletal radiologists retrospectively reviewed in consensus the photographs of anatomic sections and dissections derived from 20 cadaveric wrists. This cadaveric study gave the two readers the opportunity to learn the anatomy and orientation of the various extrinsic and intrinsic carpal ligaments and, thus, to develop a US protocol to facilitate the recognition of each carpal ligament. In the second part of the study, these two radiologists prospectively and independently evaluated the visibility of extrinsic and intrinsic carpal ligaments in 30 wrists of volunteers, using the same US protocol. With regard to extrinsic carpal ligaments, the radioscaphocapitate ligament (partially visible, 38%; completely visible, 62%), the radiolunotriquetral ligament (partially visible, 27%; completely visible, 73%), the palmar ulnotriquetral ligament (partially visible, 12%; completely visible, 88%), and the dorsal radiotriquetral ligament (partially visible, 7%; completely visible, 93%) were visualized at US. The dorsal ulnotriquetral ligament (partially visible, 21%; completely visible, 74%), the ulnolunate ligament (partially visible, 5%; completely visible, 70%), and the radial collateral ligament (partially visible, 18%; completely visible, 12%) were more difficult to recognize. The radioscapholunate ligament was never seen. With regard to intrinsic carpal ligaments, the dorsal (partially visible, 11%; completely visible, 89%) and palmar (partially visible, 38%; completely visible, 62%) scaphotriquetral ligaments as well as the dorsal scapholunate ligament (partially visible, 3%; completely visible, 97%) were visualized at US. The dorsal lunotriquetral ligament (partially visible, 39%; completely visible, 61%) and the palmar scapholunate ligaments (partially visible, 12%; completely visible, 81%) were more difficult to recognize.

Full Text Available BackgroundAn anatomical analysis of the transverse carpal ligament (TCL and the surrounding structures might help in identifying effective measures to minimize complications. Here, we present a surgical technique based on an anatomical study that was successfully applied in clinical settings.MethodsUsing 13 hands from 8 formalin-fixed cadavers, we measured the TCL length and thickness, correlation between the distal wrist crease and the proximal end of the TCL, and distance between the distal end of the TCL and the palmar arch; the TCL cross sections and the thickest parts were also examined. Clinically, fasciotomy was performed on the relevant parts of 15 hands from 13 patients by making a minimally invasive incision on the distal wrist crease. Postoperatively, a two-point discrimination check was conducted in which the sensations of the first, second, and third fingertips and the palmar cutaneous branch injuries were monitored (average duration, 7 months.ResultsIn the 13 cadaveric hands, the distal wrist crease and the proximal end of the TCL were placed in the same location. The average length of the TCL and the distance from the distal TCL to the superficial palmar arch were 35.30±2.59 mm and 9.50±2.13 mm, respectively. The thickest part of the TCL was a region 25 mm distal to the distal wrist crease (average thickness, 4.00±0.57 mm. The 13 surgeries performed in the clinical settings yielded satisfactory results.ConclusionsThis peri-TCL anatomical study confirmed the safety of fasciotomy with a minimally invasive incision of the distal wrist crease. The clinical application of the technique indicated that the minimally invasive incision of the distal wrist crease was efficacious in the treatment of the carpal tunnel syndrome.

Fractures of the hook of the hamate are a rare event. The fracture cannot always be detected clinically and standard radiographs do not always provide an overlap-free image of the hook of the hamate, so that fractures can easily be overlooked. The objective of the present study was to examine if the sensitivity of detecting hamulus ossis hamati fractures can further be improved by a modified conventional radiographic projection. After dissection of the hook of the hamate on 10 cadaver hands, a fracture was produced close to the base using a surgical chisel. Conventional radiographs were then performed in four different projections (dorso-palmar, lateral, carpal-tunnel and oblique view). The oblique view was obtained in a 45 supination position, slight extension and radial duction, with the tube tilted from distal to proximal by 30 . An axial spiral CT was used as a reference for detection of the fracture. The highest sensitivity of the conventional radiographs, with 8/10 identified fractures (80%), was achieved by the oblique view. The carpal-tunnel view with 4/10 (40%) and the dorso-palmar projection with 3/10 (30%) were much lower. All fractures were missed in the lateral projection. If all of the conventional radiographic projections are taken into account, the sensitivity is increased to 90%. All of the fractures were reliably detected in the axial CT-image. If a hamulus ossis hamati fracture is suspected clinically, in addition to the dorso-palmar and carpal-tunnel view, the special oblique view described here should be performed as a third projection plane, while the lateral view can be dispensed with. However, even if all projections are taken into account, a negative finding in the conventional radiographic imaging does not exclude a fracture with absolute certainty. In such cases, a CT or MRI should be performed to exclude a fracture. (orig.)

Stage IV melanoma exhibits a diverse range of tumor biology from indolent to aggressive disease. Many important prognostic factors have already been identified. Despite this, the behavior of metastatic melanoma remains difficult to predict. We sought to determine if any primary tumor characteristics affect survival following the diagnosis of stage IV melanoma. All patients diagnosed with stage IV melanoma between January 2003 and December 2012 were identified from the Victorian Melanoma Service database. Retrospective chart review was performed to collect data on primary tumor characteristics (thickness, ulceration, mitotic rate, melanoma subtype, or occult primary). Known and suspected prognostic factors were additionally collected (time to diagnosis of stage IV disease, age, sex, stage, receipt of chemotherapy, and era of recurrence). The effect of primary tumor characteristics on overall survival from the date of diagnosis of stage IV disease was assessed. A total of 227 patients with a median follow-up of 5 years from diagnosis of stage IV disease were identified. Median overall survival of the cohort was 250 days.Of the primary tumor characteristics assessed, only tumor thickness affected survival from diagnosis of stage IV disease, hazard ratio=1.09 (1.02 to 1.16), P=0.008. This remained significant in multivariate analysis, P=0.007. Other primary tumor characteristics did not significantly influence survival. Primary tumor thickness is a significant prognostic factor in stage IV melanoma. Our data suggest that the biology of the primary melanoma may persist to influence the behavior of metastatic disease.

Infrared thermography based on artificial intelligence for carpal tunnel syndrome diagnosis.

Science.gov (United States)

Jesensek Papez, B; Palfy, M; Turk, Z

2008-01-01

Thermography for the measurement of surface temperatures is well known in industry, although is not established in medicine despite its safety, lack of pain and invasiveness, easy reproducibility, and low running costs. Promising results have been achieved in nerve entrapment syndromes, although thermography has never represented a real alternative to electromyography. Here an attempt is described to improve the diagnosis of carpal tunnel syndrome with thermography using a computer-based system employing artificial neural networks to analyse the images. Method reliability was tested on 112 images (depicting the dorsal and palmar sides of 26 healthy and 30 pathological hands), with the hand divided into 12 segments and compared relative to a reference. Palmar segments appeared to have no beneficial influence on classification outcome, whereas dorsal segments gave improved outcome with classification success rates near to or over 80%, and finger segments influenced by the median nerve appeared to be of greatest importance. These are preliminary results from a limited number of images and further research will be undertaken as our image database grows.

Ultraviolet and visible light penetration of epidermis

Eggset, G.; Kavli, G.; Volden, G.; Krokan, H.

1984-01-01

Light penetration in untanned skin and skin tanned with UVB (middlewave ultraviolet light) or PUVA (Psoralen photochemotherapy) was compared. Transmission at different wavelengths was measured through sheets of intact epidermis isolated by a suction blister technique. Thick epidermis was collected from a newly formed palmar friction bulla. For these studies a monochromator was used and the range of wavelengths examined was 280-700 nm. The transmission was considerably lower in tanned skin and the difference was most pronounced in the UV range. In the UVB range (290-320 nm), transmission was 13-43% for untanned epidermis, 8-12% for UVB tanned and slightly lower for PUVA tanned epidermis. At wavelengths below 325 nm only a few per cent of light penetrate through thick palmar epidermis. Both UVB and PUVA induce increased melanin content and thickening of the epidermis. Our results indicate that melanin is the most efficient protection against UVA while thickening of epidermis may be as important as the increased melanin content for the protection of living basal cells against the harmful UVB rays.

A new species of Cymadusa Savigny, 1816 (Crustacea: Amphipoda: Ampithoidae from northeastern Brazil

Directory of Open Access Journals (Sweden)

Luiz F. Andrade

Full Text Available A new species of the amphipod family Ampithoidae Stebbing, 1899 is described from the northeastern Brazilian waters. The new described taxon is grouped in the genus Cymadusa Savigny, 1816, since it presents all the diagnostic characteristics of the genus. The examined material was collected by scuba diving in the Rocas Atoll, off Rio Grande do Norte state coast, Camamu Bay and Todos os Santos Bay, Bahia state. The new species described here is close to C. filosa Savigny, 1816, type species of the genus, by presenting anterior margin of gnathopod 1 poorly setose, male gnathopod 2 densely setose, with palmar corner not defined by a spine and dactylus subequal in length to palm, being considered part of the C. filosa complex. Among the species of this complex, the one which most resembles to the new taxon is C. imbroglio Rabindranath, 1972, which is distinguished by the absence of both the trapezoid process in the palm and spine at the palmar corner in the gnathopod 2. This is the second species of the genus Cymadusa recorded from Brazilian waters.

Riggs, C.M.; Whitehouse, G.H.; Boyde, A.

1999-01-01

This study examined material from Thoroughbred horses, the majority of which had been in race training, for evidence of pathology in the third metacarpal (McIII) and third metatarsal (MtIII) bones which might be related to the occurrence of distal condylar fractures. Whole bone samples were studied and documented by macrophotography prior to macroradiography and computed tomographic (CT) imaging. Microradiographs were made from 100 microm thick mediolateral sections cut perpendicular to the dorsal and palmar/plantar articular surfaces of distal condylar regions of McIII and MtIII. Blocks were prepared for morphological imaging using the backscattered electron mode of scanning electron microscopy (BSE SEM). Linear defects in mineralised articular cartilage and subchondral bone were found in the palmar/plantar aspects of the condylar grooves adjacent to the sagittal ridge. These were closely related to the pattern of densification of the subchondral bone and were associated with intense focal remodelling of the immediately adjacent and subjacent bone. Parasagittal fractures of the condyles originated in similar defects. A unifying hypothesis for the aetiopathogenesis of these fractures is presented

Konaka, C.; Okunaka, T.; Sakai, H.; Furukawa, K.; Hayata, Y.; Kato, H.

1992-01-01

In recent years, multiple primary lung cancers have been reported with greater frequency. As for the treatment of multiple primary lung cancer, operative excision is usually difficult for all lesions due to problems of pulmonary function. PDT is a good therapeutic modality in the treatment of multiple primary lung cancer, especially central type lung cancer, for preservation of lung function. Since 1980, 50 patients of endoscopically-evaluated early stage lung cancers have been treated with PDT at Tokyo Medical College. Within this group, 16 patients were classified as having multiple primary lung cancers. This paper evaluates the effectiveness of PDT in the treatment of these patients with multiple primary bronchogenic carcinoma. (author). 6 refs., 2 tabs

Primary care training and the evolving healthcare system.

With growing numbers of patient-centered medical homes and accountable care organizations, and the potential implementation of the Patient Protection and Affordable Care Act, the provision of primary care in the United States is expanding and changing. Therefore, there is an urgent need to create more primary-care physicians and to train physicians to practice in this environment. In this article, we review the impact that the changing US healthcare system has on trainees, strategies to recruit and retain medical students and residents into primary-care internal medicine, and the preparation of trainees to work in the changing healthcare system. Recruitment methods for medical students include early preclinical exposure to patients in the primary-care setting, enhanced longitudinal patient experiences in clinical clerkships, and primary-care tracks. Recruitment methods for residents include enhanced ambulatory-care training and primary-care programs. Financial-incentive programs such as loan forgiveness may encourage trainees to enter primary care. Retaining residents in primary-care careers may be encouraged via focused postgraduate fellowships or continuing medical education to prepare primary-care physicians as both teachers and practitioners in the changing environment. Finally, to prepare primary-care trainees to effectively and efficiently practice within the changing system, educators should consider shifting ambulatory training to community-based practices, encouraging resident participation in team-based care, providing interprofessional educational experiences, and involving trainees in quality-improvement initiatives. Medical educators in primary care must think innovatively and collaboratively to effectively recruit and train the future generation of primary-care physicians. © 2012 Mount Sinai School of Medicine.

Primary venous leiomyosarcoma is rare. We report the case of a primary leiomyosarcoma of the left innominate vein, with neoplastic thrombus extending into the left jugular and subclavian veins. The tumor was curatively resected en bloc with anterior mediastinal and laterocervical lymphatics, through a median sternotomy prolonged into left cervicotomy. Primary venous sarcomas may be associated with prolonged survival in individual cases, with curative resection recommended as the standard treatment, in the absence of distant spread.

Primary progressive aphasia and apraxia of speech.

Jung, Youngsin; Duffy, Joseph R; Josephs, Keith A

2013-09-01

Primary progressive aphasia is a neurodegenerative syndrome characterized by progressive language dysfunction. The majority of primary progressive aphasia cases can be classified into three subtypes: nonfluent/agrammatic, semantic, and logopenic variants. Each variant presents with unique clinical features, and is associated with distinctive underlying pathology and neuroimaging findings. Unlike primary progressive aphasia, apraxia of speech is a disorder that involves inaccurate production of sounds secondary to impaired planning or programming of speech movements. Primary progressive apraxia of speech is a neurodegenerative form of apraxia of speech, and it should be distinguished from primary progressive aphasia given its discrete clinicopathological presentation. Recently, there have been substantial advances in our understanding of these speech and language disorders. The clinical, neuroimaging, and histopathological features of primary progressive aphasia and apraxia of speech are reviewed in this article. The distinctions among these disorders for accurate diagnosis are increasingly important from a prognostic and therapeutic standpoint.

Mullangi, Samyukta; Saint, Sanjay

2017-03-01

Addressing the mounting primary care shortage in the United States has been a focus of educators and policy makers, especially with the passage of the Affordable Care Act in 2010 and the Medicare Access and CHIP Reauthorization Act in 2015, placing increased pressure on the system. The Association of American Medical Colleges recently projected a shortage of as many as 65,000 primary care physicians by 2025, in part because fewer than 20% of medical students are picking primary care for a career. We examined the issue of attracting medical students to primary care through the lens of organizational behavior theory. Assuming there are reasons other than lower income potential for why students are inclined against primary care, we applied various principles of the Herzberg 2-factor theory to reimagine the operational flow and design of primary care. We conclude by proposing several solutions to enrich the job, such as decreasing documentation requirements, reducing the emphasis on specialty consultations, and elevating physicians to a supervisory role.

During the 1980s and 1990s, innovations in the organization, funding, and delivery of primary health care in Canada were at the periphery of the system rather than at its core. In the early 2000s, a new policy environment emerged. This policy analysis examines primary health care reform efforts in Canada during the last decade, drawing on descriptive information from published and gray literature and from a series of semistructured interviews with informed observers of primary health care in Canada. Primary health care in Canada has entered a period of potentially transformative change. Key initiatives include support for interprofessional primary health care teams, group practices and networks, patient enrollment with a primary care provider, financial incentives and blended-payment schemes, development of primary health care governance mechanisms, expansion of the primary health care provider pool, implementation of electronic medical records, and quality improvement training and support. Canada's experience suggests that primary health care transformation can be achieved voluntarily in a pluralistic system of private health care delivery, given strong government and professional leadership working in concert. © 2011 Milbank Memorial Fund.

Primary congenital hypothyroidism is frequently seen endocrine disorder and one of the preventable cause of mental retardation. Aim of study was to evaluate the frequency of permanent/transient hypothyrodism, and to detect underlying reason to identfy any marker which carries potential to discriminate permanent/transient form. Forty eight cases older than 3 years of age, diagnosed as primary congenital hypothyroidism and started thyroxin therapy in newborn-period, and followed up between January 2007-June 2013 were included in the study. Thyroid hormon levels were evaluated and thyroid ultrasonography was performed in cases who are at the end of their 3 years of age, after 6 weeks of thyroxine free period. Thyroid sintigraphy was performed if serum thyroid-stimulating hormone was high (≥ 5 mIU/mL) and perchlorate discharge test was performed if uptake was normal or increased on sintigraphy. Cases with thyroid-stimulating hormone levels ≥ 5 mIU/mL were defined as permanent primary congenital hypothyroidism group and as transient primary congenital hypothyroidism group with normal thyroid hormones during 6 months. The mean age was 3.8±0.7 years. Mean diagnosis age was 16.6±6.5 days and 14 cases (29.2%) were diagnosed by screening program of Ministry of Health. There were 23 cases (14F, 9M) in permanent primary congenital hypothyroidism group and 12 (52.2%) of them were dysgenesis (8 hypoplasia, 4 ectopia), and 11 (47.8%) dyshormonogenesis. In transient primary congenital hypothyroidism group, there were 25 cases (17M, 8F). The mean thyroid-stimulating hormone levels at diagnosis were similar in two groups. The mean thyroxin dose in permanent primary congenital hypothyroidism group was significantly higher than transient group at the time of thyroxin cessation (2.1±0.7, 1.5±0.5 mg/kg/d, respectively, p=0.004). Thyroxin dose ≥1.6 mcg/kg/d was 72% sensitive and 69.6% specific for predicting permenant primary congenital hypothyroidism. Transient primary

The primary health care in rural areas in Austria is currently determined by challenges such as ageing of the population, the shift towards chronic and age-related illnesses, the specialist medical and hospital-related education and training of physicians' as well growing widespread difficulty of staffing doctor's office. The objective is to realize a general practitioner centered and team-oriented primary health care (PHC) approach by establishing networked primary health care in rural areas of Austria. Using literature research, online survey, expert interviews and expert workshops, we identified different challenges in terms of primary health care in rural areas. Further, current resources and capacities of primary health care in rural areas were identified using the example of the district of Rohrbach. Twelve design dimensions and 51 relevant measurement indicators of a PHC network were delineated and described. Based on this, 12 design approaches of PHC concept for the GP-centered and team-oriented primary health care in rural areas have been developed.

Shrivastava et all concluded that assessment mechanism for the achievement of objectives for the suggested RKS model was not successful (1. Hereby I would like to emphasize the importance of quality assessment (QA especially in the era of newly established primary care implementations in our country. Promotion of quality has been fundamental part of primary care health services. Nevertheless variations in quality of care exist even in the developed countries. Accomplishment of quality in the primary care has some barriers like administration and directorial factors, absence of evidence-based medicine practice lack of continuous medical education. Quality of health care is no doubt multifaceted model that covers all components of health structures and processes of care. Quality in the primary care set up includes patient physician relationship, immunization, maternal, adolescent, adult and geriatric health care, referral, non-communicable disease management and prescribing (2. Most countries are recently beginning the implementation of quality assessments in all walks of healthcare. Organizations like European society for quality and safety in family practice (EQuiP endeavor to accomplish quality by collaboration. There are reported developments and experiments related to the methodology, processes and outcomes of quality assessments of health care. Quality assessments will not only contribute the accomplishment of the program / project but also detect the areas where obstacles also exist. In order to speed up the adoption of QA and to circumvent the occurrence of mistakes, health policy makers and family physicians from different parts of the world should share their experiences. Consensus on quality in preventive medicine implementations can help to yield

The uptake of family health teams in Ontario has been tremendous. And the creation of group practices in primary care has taken root in other provinces as well. For many people, being involved with something new is exciting. At the same time, once they are committed, they discover the challenges that can be simultaneously exhilarating and frustrating. This issue of Healthcare Quarterly offers two articles that provide interesting reflections on what has been learned so far from the perspectives of both team leadership and the team members themselves within a transforming primary care system.

Primary decomposition of torsion R[X]-modules

Directory of Open Access Journals (Sweden)

William A. Adkins

1994-01-01

Full Text Available This paper is concerned with studying hereditary properties of primary decompositions of torsion R[X]-modules M which are torsion free as R-modules. Specifically, if an R[X]-submodule of M is pure as an R-submodule, then the primary decomposition of M determines a primary decomposition of the submodule. This is a generalization of the classical fact from linear algebra that a diagonalizable linear transformation on a vector space restricts to a diagonalizable linear transformation of any invariant subspace. Additionally, primary decompositions are considered under direct sums and tensor product.

(1) To describe New Zealand's primary care system (2) to compare New Zealand to other Anglo-American members of the OECD with respect to the adequacy of primary care, and (3) to assess the cost-efficiency and effectiveness of New Zealand's system by comparing health spending and health indicators relevant to primary care. A cross-national comparison of primary care, health spending and health indicators in New Zealand, Australia, Canada, the United Kingdom and the United States of America. Main outcome measures were health spending measured in purchasing power parties. Health indicators: mean life expectancy in years, years of potential life lost and infant mortality rates. New Zealand's primary care system ranked below the UK, above the USA and similar to Canada and Australia. Favourable characteristics of New Zealand's primary care system were the use of generalists as the predominant type of practitioner and the low proportion of active physicians who were specialists. Compared to the other countries, New Zealand scored poorly for financial that are necessary for the practise of good primary care. New Zealand and the UK had the lowest spending per capita on health care. New Zealand and the USA scored lowest for all three of the health care indicators. The quality of primary care in New Zealand is limited by barriers to access to care and the intermediate level of practise characteristics essential to primary care. Compared to other AngloAmerican OECD nations, New Zealand has relatively low levels of national health expenditure. In order to improve the quality of primary care, future reform should aim to facilitate access to care, increase the gatekeeping role of primary care physicians, and promote the practise characteristics essential to primary care.

2008-09-01

Full Text Available Abstract Background A strong and self confident primary care workforce can deliver the highest quality care and outcomes equitably and cost effectively. To meet the increasing demands being made of it, primary care needs its own thriving research culture and knowledge base. Methods Review of recent developments supporting primary care clinical research. Results Primary care research has benefited from a small group of passionate leaders and significant investment in recent decades in some countries. Emerging from this has been innovation in research design and focus, although less is known of the effect on research output. Conclusion Primary care research is now well placed to lead a broad re-vitalisation of academic medicine, answering questions of relevance to practitioners, patients, communities and Government. Key areas for future primary care research leaders to focus on include exposing undergraduates early to primary care research, integrating this early exposure with doctoral and postdoctoral research career support, further expanding cross disciplinary approaches, and developing useful measures of output for future primary care research investment.

Third sector primary care for vulnerable populations.

Science.gov (United States)

Crampton, P; Dowell, A; Woodward, A

2001-12-01

This paper aims to describe and explain the development of third sector primary care organisations in New Zealand. The third sector is the non-government, non-profit sector. International literature suggests that this sector fulfils an important role in democratic societies with market-based economies, providing services otherwise neglected by the government and private for-profit sectors. Third sector organisations provided a range of social services throughout New Zealand's colonial history. However, it was not until the 1980s that third sector organisations providing comprehensive primary medical and related services started having a significant presence in New Zealand. In 1994 a range of union health centres, tribally based Mäori health providers, and community-based primary care providers established a formal network -- Health Care Aotearoa. While not representing all third sector primary care providers in New Zealand, Health Care Aotearoa was the best-developed example of a grouping of third sector primary care organisations. Member organisations served populations that were largely non-European and lived in deprived areas, and tended to adopt population approaches to funding and provision of services. The development of Health Care Aotearoa has been consistent with international experience of third sector involvement -- there were perceived "failures" in government policies for funding primary care and private sector responses to these policies, resulting in lack of universal funding and provision of primary care and continuing patient co-payments. The principal policy implication concerns the role of the third sector in providing primary care services for vulnerable populations as a partial alternative to universal funding and provision of primary care. Such an alternative may be convenient for proponents of reduced state involvement in funding and provision of health care, but may not be desirable from the point of view of equity and social cohesion

Primary omental pregnancy

International Nuclear Information System (INIS)

Yildizhan, R.; Kurdoglu, M.; Kolusari, A.; Erten, R.

2008-01-01

Omental pregnancy is a rare form of ectopic pregnancy and can be seen primarily or secondary to a tubal pregnancy. A 25-yeal-old woman presented with abdominal distention with pain and anemia without vaginal bleeding. After a provisional diagnosis of ruptured ectopic pregnancy, laparotomy was performed. On surgical exploration, the bilateral tubes and ovaries were intact, however, an omental pregnancy was detected as the cause of hemoperitoneum. Partial omentectomy was performed. Although most cases are secondary, presented here is an additional case of primary omental pregnancy at 12 weeks according to Studdiford's criteria. Histological evidence of neovascularization into the supporting tissue confirmed our diagnosis. A primary omental pregnancy should always be considered as a possible explanation for severe hemoperitoneum in ectopic pregnancies presenting with acute abdomen and with intact adnexes on surgical exploration.

Thappa, D M; Sethuraman, G; Kumar, G R; Elangovan, S

2000-02-01

Pachydermoperiostosis (PDP), a rare genodermatosis, occurred in a 38-year-old Indian male. He presented with progressive thickening of the skin on the face and scalp of 15 years duration. Widening of his wrists and ankles and broadening of the fingers and toes had also developed since then. He was born of a consanguineous marriage and had no family history of a similar disorder. He had the typical findings of complete form of PDP including cutis verticis gyrata, coarse facial features, clubbing of the digits in the skin, and periostosis and cortical thickening at the distal ends of long bones of the extremities and small bones of the hands and feet. PDP has two different forms--primary and secondary. These two entities are differentiated by family history and presence or absence of a primary lesion, usually in the lungs. Clinically, in secondary PDP, the cutaneous findings (pachydermia, seborrhoea, oiliness) are less severe than primary PDP; osteoarthropathy is more severe and painful in secondary PDP, especially with congenital heart disease. The present case was suffering from primary PDP that had expressed itself in its complete form.

Papillon-Lefevre syndrome: A case report of 2 affected siblings

Full Text Available Papillon-Lefèvre syndrome (PLS is a very rare syndrome of autosomal recessive inheritance characterized by palmar-plantar hyperkeratosis and early onset periodontitis, leading to premature loss of both primary and permanent dentitions. Various etiopathogenic factors are associated with the syndrome, but a recent report has suggested that the condition is linked to x mutations of the cathepsin C gene. The purpose of this report is to describe two cases of PLS in the same family who presented to the Department of Dentistry of Dr. R. P. Government Medical College at Tanda, Kangra (Himachal Pradesh with a chief complaint of mobility and rapid loss of teeth. Hyperkeratosis of palms and soles was present. On intraoral examination, there was severe gingival inflammation, abscess formation, and deep periodontal pockets with mobility of teeth. Histopathological examination of the specimen taken from the thickened skin was reported to be consistent with PLS. The dental treatment comprised oral prophylaxis, scaling and root planning, antibiotic therapy, instructions on oral hygiene, restorations, extraction of hopelessly affected teeth, and prosthetic rehabilitation.

1998-12-31

The use of a Tetra Deep Bed filter demonstration unit to treat primary effluent (Primary Effluent Filtration, PEF) was investigated. PEF proved capable of achieving the UWWTD primary standard, even when the primary stage performs poorly, but is not a cost-effective alternative to chemically assisted settlement. Results demonstrated that using a 1.5 to 2.2 mm grade medium, a filtration rate of 5 m/h, three backwashes a day and dosing 40 mg/l of PAXXL60 (a polyaluminium silicte) an average effluent quality of 20 mg/l BOD and 15 mgl/l total solid could be achieved. UV disinfection produced an effluent which complied with the Bathing Water Directive imperative requirement. A high enterovirus kill was also achieved. However, considerable additional work would be required before PEF could be considered suitable for full-scale applications. (orig.)

Primary mural endocarditis is an extremely rare infection in which nonvalvular endocardial involvement is seen without any cardiac structural abnormalities such as ventricular septal defects. The rapid and precise diagnosis of this disease remains challenging. We present 2 cases (67- and 47-year-old male patients) of pathologically confirmed primary mural endocarditis that could have been detected by initial transthoracic echocardiography in the emergency department. Transthoracic echocardiography and transesophageal echocardiography play critical roles in the early recognition and confirmation of primary mural endocarditis. © 2017 by the American Institute of Ultrasound in Medicine.

AimThe aim of this paper is to examine Canadian key informants' perceptions of intrapersonal (within an individual) and interpersonal (among individuals) factors that influence successful primary care and public health collaboration. Primary health care systems can be strengthened by building stronger collaborations between primary care and public health. Although there is literature that explores interpersonal factors that can influence successful inter-organizational collaborations, a few of them have specifically explored primary care and public health collaboration. Furthermore, no papers were found that considered factors at the intrapersonal level. This paper aims to explore these gaps in a Canadian context. This interpretative descriptive study involved key informants (service providers, managers, directors, and policy makers) who participated in one h telephone interviews to explore their perceptions of influences on successful primary care and public health collaboration. Transcripts were analyzed using NVivo 9.FindingsA total of 74 participants [from the provinces of British Columbia (n=20); Ontario (n=19); Nova Scotia (n=21), and representatives from other provinces or national organizations (n=14)] participated. Five interpersonal factors were found that influenced public health and primary care collaborations including: (1) trusting and inclusive relationships; (2) shared values, beliefs and attitudes; (3) role clarity; (4) effective communication; and (5) decision processes. There were two influencing factors found at the intrapersonal level: (1) personal qualities, skills and knowledge; and (2) personal values, beliefs, and attitudes. A few differences were found across the three core provinces involved. There were several complex interactions identified among all inter and intra personal influencing factors: One key factor - effective communication - interacted with all of them. Results support and extend our understanding of what influences

We report a case of primary multifocal osseous lymphoma in a 6-year-old girl presenting with multifocal osteolytic lesions without systemic symptoms or identifiable non-osseous primary tumor. The differential diagnoses for such a presentation include histiocytosis X, chronic recurrent multifocal osteomyelitis, acute lymphoblastic leukemia, metastatic disease, and primary bone lymphoma. Although non-Hodgkin lymphoma is common in the pediatric population, its presentation as a primary bone tumor, especially with multifocal disease, is extremely rare and is frequently misdiagnosed. We hope that awareness of this entity will help radiologists achieve timely diagnosis and intervention. (orig.)

McIsaac, Michelle L; Goeree, Ron; Brophy, James M

2007-01-01

This study discusses the value of primary data collection as part of health technology assessment (HTA). Primary data collection can help reduce uncertainty in HTA and better inform evidence-based decision making. However, methodological issues such as choosing appropriate study design and practical concerns such as the value of collecting additional information need to be addressed. The authors emphasize the conditions required for successful primary data collection in HTA: experienced researchers, sufficient funding, and coordination among stakeholders, government, and researchers. The authors conclude that, under specific conditions, primary data collection is a worthwhile endeavor in the HTA process.

Cosmic-ray antimatter - A primary origin hypothesis

The present investigation is concerned with the possibility that the observed cosmic-ray protons are of primary extragalactic origin, taking into account the significance of the current antiproton data. Attention is given to questions regarding primary antiprotons, antihelium fluxes, and the propagation of extragalactic cosmic rays. It is concluded that the primary origin hypothesis should be considered as a serious alternative explanation for the cosmic-ray antiproton fluxes. Such extragalactic primary origin can be considered in the context of a baryon symmetric domain cosmology. The fluxes and propagation characteristics suggested are found to be in rough agreement with the present antiproton data.

Full Text Available CONTEXTUALIZAÇÃO: Instrumentos de medida devem ser analisados quanto a sua utilidade clínica e científica em diferentes populações. Apesar de o teste da força de preensão palmar (FPP ser amplamente utilizado, pouco foi investigado quanto a sua confiabilidade ao ser utilizado em idosos com demência e em qual grau de demência seria inviabilizado o seu uso. OBJETIVO: Avaliar a confiabilidade teste-reteste da FPP em idosos com diferentes graus de demência. MÉTODO: Realizou-se uma avaliação dos aspectos cognitivos de 76 idosos com demência e uma entrevista com o cuidador, permitindo a classificação do idoso segundo os critérios da Escala Clínica de Demência (Clinical dementia rating - CDR. Para essas avaliações, foram utilizados o Miniexame do Estado Mental e os questionários Pfeffer, Lawton e Katz. Vinte idosos foram classificados como grau questionável (83,4±5,8 anos; 19, como leve (82,4±6,8 anos; 19, como moderado (85,8±5,6 anos e 18, como grave (84,0±5,1 anos. Os idosos tiveram a FPP avaliada por meio de um dinamômetro hidráulico JAMAR e, após uma semana, foram reavaliados. A confiabilidade foi estimada pelo Coeficiente de Correlação Intraclasse (ICC. O nível de significância foi α=0,05. RESULTADOS: A confiabilidade teste-reteste foi excelente para os grupos que apresentaram o CDR questionável (ICC=0,975; p=0,001, leve (ICC=0,968; p=0,002 e moderado (ICC=0,964; p=0,001. A análise do grupo com CDR grave mostrou não haver uma significância estatística e um ICC baixo (ICC=0,415; p=0,376. CONCLUSÃO: O teste de FPP apresenta excelente confiabilidade ao ser utilizado em idosos com demências questionável, leve e moderada, viabilizando seu uso em pesquisas. Já em idosos classificados como graves, seu uso não é recomendado visto que a confiabilidade da medida é baixa e, portanto, sem relevância clínica para uso na prática.BACKGROUND: Measuring instruments should have their scientific and clinical value

Os idosos tiveram a FPP avaliada por meio de um dinamômetro hidráulico JAMAR e, após uma semana, foram reavaliados. A confiabilidade foi estimada pelo Coeficiente de Correlação Intraclasse (ICC. O nível de significância foi α=0,05. RESULTADOS: A confiabilidade teste-reteste foi excelente para os grupos que apresentaram o CDR questionável (ICC=0,975; p=0,001, leve (ICC=0,968; p=0,002 e moderado (ICC=0,964; p=0,001. A análise do grupo com CDR grave mostrou não haver uma significância estatística e um ICC baixo (ICC=0,415; p=0,376. CONCLUSÃO: O teste de FPP apresenta excelente confiabilidade ao ser utilizado em idosos com demências questionável, leve e moderada, viabilizando seu uso em pesquisas. Já em idosos classificados como graves, seu uso não é recomendado visto que a confiabilidade da medida é baixa e, portanto, sem relevância clínica para uso na prática.BACKGROUND: Measuring instruments should have their scientific and clinical value

Hyperthyroidism (primary)

OpenAIRE

Nygaard, Birte

2010-01-01

Hyperthyroidism is characterised by high levels of serum thyroxine and triiodothyronine, and low levels of thyroid-stimulating hormone (TSH). Thyrotoxicosis is the clinical effect of high levels of thyroid hormones, whether or not the thyroid gland is the primary source.The main causes of hyperthyroidism are Graves' disease, toxic multinodular goitre, and toxic adenoma.About 20 times more women than men have hyperthyroidism.

Schmidt, Karen L; Lingler, Jennifer H; Schulz, Richard

Primary care visits of patients with Alzheimer's disease (AD) often involve communication among patients, family caregivers, and primary care physicians (PCPs). The objective of this study was to understand the nature of each individual's verbal participation in these triadic interactions. To define the verbal communication dynamics of AD care triads, we compared verbal participation (percent of total visit speech) by each participant in patient/caregiver/PCP triads. Twenty-three triads were audio taped during a routine primary care visit. Rates of verbal participation were described and effects of patient cognitive status (MMSE score, verbal fluency) on verbal participation were assessed. PCP verbal participation was highest at 53% of total visit speech, followed by caregivers (31%) and patients (16%). Patient cognitive measures were related to patient and caregiver verbal participation, but not to PCP participation. Caregiver satisfaction with interpersonal treatment by PCP was positively related to caregiver's own verbal participation. Caregivers of AD patients and PCPs maintain active, coordinated verbal participation in primary care visits while patients participate less. Encouraging verbal participation by AD patients and their caregivers may increase the AD patient's active role and caregiver satisfaction with primary care visits.

Primary stabbing headache.

Pareja, Juan A; Sjaastad, Ottar

2010-01-01

Primary stabbing headache is characterized by transient, cephalic ultrashort stabs of pain. It is a frequent complaint with a prevalence of 35.2%, a female preponderance, and a mean age of onset of 28 years (Vågå study). Attacks are generally characterized by moderate to severe, jabbing or stabbing pain, lasting from a fraction of a second to 3s. Attack frequency is generally low, with one or a few attacks per day. The paroxysms generally occur spontaneously, during daytime. Most patients exhibit a sporadic pattern, with an erratic, unpredictable alternation between symptomatic and non-symptomatic periods. Paroxysms are almost invariably unilateral. Temporal and fronto-ocular areas are most frequently affected. Attacks tend to move from one area to another, in either the same or the opposite hemicranium. Jabs may be accompanied by a shock-like feeling and even by head movement - "jolts" -or vocalization. On rare occasions, conjunctival hemorrhage and monocular vision loss have been described as associated features. Primary stabbing headache may concur, synchronously or independently, with other primary headaches. In contrast to what is the case in adults, in childhood it is not usually associated with other headaches. Treatment is rarely necessary. Indomethacin, 75-150 mg daily, may seem to be of some avail. Celecoxib, nifedipine, melatonin, and gabapentin have been reported to be effective in isolated cases and small series of patients. The drug studies need corroboration. Copyright © 2011 Elsevier B.V.

These rare lymphomas are usually presented in the clinic as disseminations secondary to chronic lymphocytic leukaemia, and the primary site is rare in the orbit. Non-Hodgkin lymphomas are a heterogeneous group of tumours. Although treatment in the IE stage is usually radiotherapy, due to its association with antiphospholipid syndrome, systemic treatment with rituximab was administered.

Radiochemical surveillance of KNK primary sodium

Stamm, H.-H.; Stade, K.Ch.

1987-05-01

Radiochemical surveillance of the KNK primary sodium has been performed now for 15 years with 953 effective full-power days. The overflow method used for sodium sampling proved to be reliable. Different crucible materials have been used for different analytical tasks. The amount of radionuclides in the primary system has not given restrictions to plant operation at any time. On-line gamma spectroscopy on pipings and components of the primary circuits was accomplished in reactor downtimes. Activity depositions on the walls were dominated by Ta-182 after KNK I operation. Main deposited activities at KNK II were Mn-54 (fresh core) and after operation with failed fuel Cs-137, in cover gas areas together with Zn-65. Efficient experimental radionuclide traps for the removal of Mn-54, Zn-65 and Cs-137 from the primary coolant were tested successfully. The dose rates on primary pipes and components of KNK I and KNK II were lower by an order of magnitude compared to water-cooled reactors. This is in good agreement with experiences from LMFBR's in other countries. The resulting average yearly accumulated personal dose rate was 0.21 man-Sv at KNK, compared to 3.9 man-Sv at German light-water-cooled power reactors

Primary extracranial vertebral artery aneurysms.

Extracranial vertebral artery aneurysms are uncommon and are usually associated with trauma or dissection. Primary cervical vertebral aneurysms are even rarer and are not well described. The presentation and natural history are unknown and operative management can be difficult. Accessing aneurysms at the skull base can be difficult and, because the frail arteries are often afflicted with connective tissue abnormalities, direct repair can be particularly challenging. We describe the presentation and surgical management of patients with primary extracranial vertebral artery aneurysms. In this study we performed a retrospective, multi-institutional review of patients with primary aneurysms within the extracranial vertebral artery. Between January 2000 and January 2011, 7 patients, aged 12-56 years, were noted to have 9 primary extracranial vertebral artery aneurysms. All had underlying connective tissue or another hereditary disorder, including Ehler-Danlos syndrome (n=3), Marfan's disease (n=2), neurofibromatosis (n=1), and an unspecified connective tissue abnormality (n=1). Eight of 9 aneurysms were managed operatively, including an attempted bypass that ultimately required vertebral ligation; the contralateral aneurysm on this patient has not been treated. Open interventions included vertebral bypass with vein, external carotid autograft, and vertebral transposition to the internal carotid artery. Special techniques were used for handling the anastomoses in patients with Ehler-Danlos syndrome. Although endovascular exclusion was not performed in isolation, 2 hybrid procedures were performed. There were no instances of perioperative stroke or death. Primary extracranial vertebral artery aneurysms are rare and occur in patients with hereditary disorders. Operative intervention is warranted in symptomatic patients. Exclusion and reconstruction may be performed with open and hybrid techniques with low morbidity and mortality.

Adenylate cyclase regulates elongation of mammalian primary cilia

International Nuclear Information System (INIS)

Ou, Young; Ruan, Yibing; Cheng, Min; Moser, Joanna J.; Rattner, Jerome B.; Hoorn, Frans A. van der

2009-01-01

The primary cilium is a non-motile microtubule-based structure that shares many similarities with the structures of flagella and motile cilia. It is well known that the length of flagella is under stringent control, but it is not known whether this is true for primary cilia. In this study, we found that the length of primary cilia in fibroblast-like synoviocytes, either in log phase culture or in quiescent state, was confined within a range. However, when lithium was added to the culture to a final concentration of 100 mM, primary cilia of synoviocytes grew beyond this range, elongating to a length that was on average approximately 3 times the length of untreated cilia. Lithium is a drug approved for treating bipolar disorder. We dissected the molecular targets of this drug, and observed that inhibition of adenylate cyclase III (ACIII) by specific inhibitors mimicked the effects of lithium on primary cilium elongation. Inhibition of GSK-3β by four different inhibitors did not induce primary cilia elongation. ACIII was found in primary cilia of a variety of cell types, and lithium treatment of these cell types led to their cilium elongation. Further, we demonstrate that different cell types displayed distinct sensitivities to the lithium treatment. However, in all cases examined primary cilia elongated as a result of lithium treatment. In particular, two neuronal cell types, rat PC-12 adrenal medulla cells and human astrocytes, developed long primary cilia when lithium was used at or close to the therapeutic relevant concentration (1-2 mM). These results suggest that the length of primary cilia is controlled, at least in part, by the ACIII-cAMP signaling pathway.

Studies have reported that non-motor symptoms are an important component of primary dystonia. However, evidence supporting cognitive impairment in primary dystonia is limited and contradictory. We applied the Chinese version of the Addenbrooke's Cognitive Examination-Revised and the Mini-Mental State Examination (MMSE) to screen for cognitive impairment in patients with primary blepharospasm. In addition, we investigated the relationship between performance on the Addenbrooke's Cognitive Examination-Revised and quality of life as measured by the Medical Outcomes Study 36-item Short-Form (SF36). The study included 68 primary blepharospasm patients and 68 controls matched by age, sex and education. The prevalence of cognitive deficits was 22.0% and 32.3% in primary blepharospasm patients group, as measured by the MMSE and the Addenbrooke's Cognitive Examination-Revised, respectively. Primary blepharospasm patents had a broad range of cognitive deficits, with the most frequently affected domains being visuospatial function (30.9%) and language (30.9%), followed by memory (27.9%), orientation/attention (26.4%) and verbal fluency (22.0%). Patients with cognitive deficits had lower total SF36 scores, especially in the subdomains of physical functioning, role-physical and social functioning, compared to those without cognitive deficits. Scores on the Addenbrooke's Cognitive Examination-Revised were significantly correlated with both the SF36 scores and the scores on the subdomains of physical functioning and social functioning. Some patients with primary blepharospasm have cognitive deficits. Poor performance on the Addenbrooke's Cognitive Examination-Revised is related to poorer quality of life.

[Primary headache and depression].

Science.gov (United States)

Gesztelyi, Gyöngyi

2004-11-28

Primary headaches--mainly tension-type headache and migraine--affect a significant portion of the population. Depression is also highly prevalent. The co-existence of a primary headache and depression in the same patient therefore might be a coincidence due to the high prevalence of these conditions, but there might be a causal relationship between them, or headaches and depression might have a common background. This review of the literature summarizes the features of the relationship between primary headaches and depression. Depression is more prevalent in headache patients than in the headache-free population. Prospective epidemiological studies suggest a common genetic, biochemical or environmental background behind primary headaches and depression. This theory is supported by the role of the same neurotransmitter systems (mostly serotonin and dopamine) in headaches as well as in depression. Comorbid depression is associated with female gender, higher age, and higher frequency of headaches. Most depression inventories--questionnaires used to screen for the severity of depressive symptoms--contain transdiagnostic items, therefore their use in their original form is limited in organic diseases: due to the somatic items they might overestimate the severity of depression. When examining a headache patient special attention should be paid to the recognition of comorbid depression. The diagnosis of suspected mood disorder could be supported by using simple screening methods, such as the original or the abbreviated versions of standard depression inventories, but the final diagnosis of major depression needs psychiatric evaluation. Quality of life of the headache patient is affected not only by the characteristics of pain (frequency, duration, severity) but also by the disability caused by headache and the associating mood disorder. Recognizing coexisting mood disorder and disability helps to make the best treatment choice for the acute and preventive treatment of

Brown, Lynsey J; Oliver-Baxter, Jodie

2016-03-01

Integrated care has the potential to deliver efficiencies and improvements in patient experiences and health outcomes. Efforts towards integrated care, especially at the primary and community health levels, have increasingly been under focus, both nationally and internationally. In Australia, regional integration is a priority, and integration of care is a task for meso-level organisations such as Primary Health Networks (PHNs). This paper seeks to provide a list of elements and questions for consideration by organisations working across primary healthcare settings, looking to enact and improve the delivery of integrated care. Six elements that consistently emerged during the development of a series of rapid reviews on integrated primary healthcare in Australia are presented in this paper. The elements identified are context, governance and leadership, infrastructure, financing, engagement, and communication. They offer a starting point for reflection in the planning and practices of organisations in their drive for continuous improvements in integrated care.

[Multiple primary colorectal cancer: Clinical aspects].

Soldatkina, N V; Kit, O I; Gevorkyan, Yu A; Milakin, A G

to define some clinical characteristics of synchronous and metachronous colorectal cancer (CRC). The investigation was concerned with the data of 150 patients with T1-4N0-2M0-1 multiple primary CRC. The clinical, biological, and morphological characteristics of synchronous and metachronous tumors were analyzed. Multiple primary tumors were 6.01% of all the cases of CRC. There was a preponderance of synchronous CRC (63.75%) with the tumor localized in the sigmoid colon and rectum. In women, synchronous colorectal tumors were more often concurrent with breast tumors; metachronous ones were detected after treatment for genital tumors. In men, synchronous colorectal tumors were more frequently concurrent with kidney cancer; metachronous ones were identified after treatment for gastric cancer. The found characteristics of multiple primary colorectal tumors may be taken in account in programs for both primary diagnosis and follow-up after treatment for malignant tumors, which will be able to improve the early detection of cancer patients and their treatment results.

FFTBM and primary pressure acceptance criterion

International Nuclear Information System (INIS)

Prosek, A.

2004-01-01

When thermalhydraulic computer codes are used for simulation in the area of nuclear engineering the question is how to conduct an objective comparison between the code calculation and measured data. To answer this the fast Fourier transform based method (FFTBM) was developed. When the FFTBM method was developed the acceptance criteria for primary pressure and total accuracy were set. In the recent study the FFTBM method was used for accuracy quantification of RD-14M large LOCA test B9401 calculations. The blind accuracy analysis indicated good total accuracy while the primary pressure criterion was not fulfilled. The objective of the study was therefore to investigate the reasons for not fulfilling the primary pressure acceptance criterion and the applicability of the criterion to experimental facilities simulating heavy water reactor. The results of the open quantitative analysis showed that sensitivity analysis for influence parameters provide sufficient information to judge in which calculation the accuracy of primary pressure is acceptable.

2012-01-01

A literature review was conducted to identify peer-reviewed articles related to primary/preferred language and interpreter-use data collection practices in hospitals, clinics, and outpatient settings to assess its completeness and quality. In January 2011, Embase (Ovid), MEDLINE (Ovid), PubMed, and Web of Science databases were searched for eligible studies. Primary and secondary inclusion criteria were applied to selected eligible articles. This extensive literature search yielded 768 articles after duplicates were removed. After primary and secondary inclusion criteria were applied, 28 eligible articles remained for data abstraction. All 28 articles in this review reported collecting primary/preferred language data, but only 18% (5/28) collected information on interpreter use. This review revealed that there remains variability in the way that primary/preferred language and interpreter use data are collected; all studies used various methodologies for evaluating and abstracting these data. Likewise, the sources from which the data were abstracted differed.

Purpose: A retrospective review analyzed the survival and freedom from relapse of patients with stage IE or IIE primary cutaneous lymphoma (non mycosis fungoides) after treatments with radiation therapy alone (XRT), chemotherapy alone (RX) or combined modality therapy (CMT). Methods and Materials: Fifty two patients with stage IE-IIE cutaneous lymphoma treated at Stanford University Hospital were reviewed. The median age was 57, with a range of 26 to 94 and a male to female ratio of 1.21:1. Patients were staged according to the Ann Arbor System. Pathology was classified according to the Working Formulation. Treatment outcomes were compared using Kaplan-Meier survival curves with a Gehan p-value test. Results: The follow up range was 6 months to 22 years (median 7 years.) Twenty one percent of patients had low grade, 63% had intermediate grade and 15% had high grade lymphoma. The most common histologic subtype was diffuse large cell lymphoma Thirty two patients received radiation alone as initial treatment and sixteen patients received combined modality as initial treatment. Four patients received chemotherapy alone. The only significant prognostic factor for survival was the stage at diagnosis. Patients with stage IE disease had a longer actuarial survival (5-yr=79%, 10-yr=71%), as compared to those with stage IIE (5-yr=49%, 10-yr=33%), (p=0.029). The only significant prognostic factor for freedom from relapse was the initial treatment. Initial combined modality treatment lead to a longer freedom from relapse compared to patients treated with radiation alone (p=0.002), (median 5 years vs. 1.2 years). Despite this, the actuarial overall survival in the combined modality group and the radiation alone group are similar (median survival 7.7 and 8 years). The efficacy of either radiation or chemotherapy as salvage treatment after radiation failure was equivalent and both salvage treatments lead to equally long survival and freedom from second relapse.

Pathology was classified according to the Working Formulation. Treatment outcomes were compared using Kaplan-Meier survival curves with a Gehan p-value test. Results: The follow up range was 6 months to 22 years (median 7 years.) Twenty one percent of patients had low grade, 63% had intermediate grade and 15% had high grade lymphoma. The most common histologic subtype was diffuse large cell lymphoma Thirty two patients received radiation alone as initial treatment and sixteen patients received combined modality as initial treatment. Four patients received chemotherapy alone. The only significant prognostic factor for survival was the stage at diagnosis. Patients with stage IE disease had a longer actuarial survival (5-yr=79%, 10-yr=71%), as compared to those with stage IIE (5-yr=49%, 10-yr=33%), (p=0.029). The only significant prognostic factor for freedom from relapse was the initial treatment. Initial combined modality treatment lead to a longer freedom from relapse compared to patients treated with radiation alone (p=0.002), (median 5 years vs. 1.2 years). Despite this, the actuarial overall survival in the combined modality group and the radiation alone group are similar (median survival 7.7 and 8 years). The efficacy of either radiation or chemotherapy as salvage treatment after radiation failure was equivalent and both salvage treatments lead to equally long survival and freedom from second relapse.

PURPOSE The paradox of primary care is the observation that primary care is associated with apparently low levels of evidence-based care for individual diseases, but systems based on primary care have healthier populations, use fewer resources, and have less health inequality. The purpose of this article is to explore, from a complex systems perspective, mechanisms that might account for the effects of primary care beyond disease-specific care. METHODS In an 8-session, participatory group model-building process, patient, caregiver, and primary care clinician community stakeholders worked with academic investigators to develop and refine an agent-based computer simulation model to test hypotheses about mechanisms by which features of primary care could affect health and health equity. RESULTS In the resulting model, patients are at risk for acute illness, acute life-changing illness, chronic illness, and mental illness. Patients have changeable health behaviors and care-seeking tendencies that relate to their living in advantaged or disadvantaged neighborhoods. There are 2 types of care available to patients: primary and specialty. Primary care in the model is less effective than specialty care in treating single diseases, but it has the ability to treat multiple diseases at once. Primary care also can provide disease prevention visits, help patients improve their health behaviors, refer to specialty care, and develop relationships with patients that cause them to lower their threshold for seeking care. In a model run with primary care features turned off, primary care patients have poorer health. In a model run with all primary care features turned on, their conjoint effect leads to better population health for patients who seek primary care, with the primary care effect being particularly pronounced for patients who are disadvantaged and patients with multiple chronic conditions. Primary care leads to more total health care visits that are due to more disease

Leadership in primary health care: an international perspective.

McMurray, Anne

2007-08-01

A primary health care approach is essential to contemporary nursing roles such as practice nursing. This paper examines the evolution of primary health care as a global strategy for responding to the social determinants of health. Primary health care roles require knowledge of, and a focus on social determinants of health, particularly the societal factors that allow and perpetuate inequities and disadvantage. They also require a depth and breadth of leadership skills that are responsive to health needs, appropriate in the social and regulatory context, and visionary in balancing both workforce and client needs. The key to succeeding in working with communities and groups under a primary health care umbrella is to balance the big picture of comprehensive primary health care with operational strategies for selective primary health care. The other essential element involves using leadership skills to promote inclusiveness, empowerment and health literacy, and ultimately, better health.

Global patterns in human consumption of net primary production

Imhoff, Marc L.; Bounoua, Lahouari; Ricketts, Taylor; Loucks, Colby; Harriss, Robert; Lawrence, William T.

2004-06-01

The human population and its consumption profoundly affect the Earth's ecosystems. A particularly compelling measure of humanity's cumulative impact is the fraction of the planet's net primary production that we appropriate for our own use. Net primary production-the net amount of solar energy converted to plant organic matter through photosynthesis-can be measured in units of elemental carbon and represents the primary food energy source for the world's ecosystems. Human appropriation of net primary production, apart from leaving less for other species to use, alters the composition of the atmosphere, levels of biodiversity, energy flows within food webs and the provision of important ecosystem services. Here we present a global map showing the amount of net primary production required by humans and compare it to the total amount generated on the landscape. We then derive a spatial balance sheet of net primary production `supply' and `demand' for the world. We show that human appropriation of net primary production varies spatially from almost zero to many times the local primary production. These analyses reveal the uneven footprint of human consumption and related environmental impacts, indicate the degree to which human populations depend on net primary production `imports' and suggest policy options for slowing future growth of human appropriation of net primary production.

From Normal Schools to Primary Teaching Schools: historic journey of primary teachers’ training schools

Joaquim António Sousa Pintassilgo

2015-02-01

Full Text Available This article provides a brief outline of the teacher training schools in Portugal for what was traditionally known as primary education, starting in the second half of the nineteenth century, when such schools began functioning regularly.  Initially know as Primary Normal Schools, these institutions were renamed in 1930 to Primary Teaching Schools. In the second half of the 1980s, under full democracy, they were phased out, their place being taken by the Higher Schools of Education. In this article we seek to chronicle their evolution with a set of reflections on the ideals professed in their day, which are to be found primarily in training contexts and in textbooks. These principles deal mainly with such issues as the social roles to be played by the primary school teachers, the values inherent to the profession, pedagogical options considered to be legitimate and educational practices thought to be exemplary. We will analyse in particular the importance that the conceptions of the New School had in the construction of identity references during the republican period and their appropriation by the conservative pedagogy that circulated in the New State. We will also take into account the process of feminization, which left its own mark on the development of this teaching sector. Finally, we will outline a model of analysis for training institutions, using as our reference the case of Portugal. 

Renal involvement in primary antiphospholipid syndrome.

Marcantoni, Carmelita; Emmanuele, Carmela; Scolari, Francesco

2016-08-01

Antiphospholipid syndrome is an autoimmune disorder characterized by recurrent venous or arterial thrombosis and/or pregnancy-related problems associated with persistently elevated levels of antiphospholipid antibodies. The kidney is a major target organ in both primary and secondary antiphospholipid syndrome. This review describes several aspects of the renal involvement in the primary form of the syndrome, in particular the histological pattern of the so-called antiphospholipid syndrome nephropathy (APSN). APSN is a vascular nephropathy characterized by small vessel vaso-occlusive lesions associated with fibrous intimal hyperplasia of interlobular arteries, recanalizing thrombi in arteries and arterioles, and focal atrophy, a constellation of morphological lesions suggestive of primary antiphospholipid syndrome.

2011-12-01

Full Text Available Primary sarcomas of the lung are rare and account for 0.5% of all primary lung tumors. There were approximately 300 cases described in the literature as of 2006. All histologic types of sarcoma were described, and the most common intrathoracic types reported were angiosarcoma, leiomyosarcoma, fibrosarcoma, hemangiopericytoma, and rhabdomyosarcoma. The biological behavior of these tumors is not well-known due to their low frequency. Leiomyosarcomas represent one of the most common subtypes encountered in the lungs, and usually occur during the sixth decade, with male predominance. Although the frequency of metastatic disease is not related to tumor size, prognosis was reported to be poorer in high-grade tumors. In comparison with other sarcomas, survival after complete resection of pulmonary leiomyosarcoma was reported as longer. We report on a patient with primary leiomyosarcoma originating from the bronchus with complete resection and long-term follow-up.

Primary repair of colon injuries is an accepted therapeutic option; however, controversy persists regarding its safety. Our objective was to report the evolution and presence of complications in patients with colon injury who underwent primary closure and to determine if the time interval (>6 h), degree of injury, contamination, anatomic site injured, PATI (Penetrating Abdominal Trauma Index) >25, and the presence of other injuries in colon trauma are associated with increased morbidity and mortality. This was a prospective, observational, longitudinal and descriptive study conducted at the Central Hospital "Dr. Ignacio Morones Prieto," San Luis Potosí, Mexico, from January 1, 2003 to December 31, 2007. We included patients with abdominal trauma with colon injury subjected to surgical treatment. chi(2) was used for basic statistical analysis. There were 481 patients with abdominal trauma who underwent surgery; 77(16.1%) had colon injury. Ninety percent (n = 69) were treated in the first 6 h; 91% (n = 70) were due to penetrating injuries, and gunshot wound accounted for 48% (n = 37). Transverse colon was the most frequently injured (38%) (n = 29). Grade I and II injuries accounted for 75.3% (n = 58). Procedures included primary repair (76.66 %) (n = 46); resection with anastomosis (8.3%) (n = 5); and colostomy (15%) (n = 9). Associated injuries were present in 76.6% (n = 59). There was some degree of contamination in 85.7% (n = 66); 82.8% (58) had PATI colon injury. Primary repair is a safe procedure for treatment of colon injuries. Patients with primary repair had lower morbidity (p <0.009). Surgery during the first 6 h (p <0.006) and in hemodynamically stable patients (p <0.014) had a lower risk of complications.

Unique properties of Drosophila spermatocyte primary cilia

Directory of Open Access Journals (Sweden)

Maria Giovanna Riparbelli

2013-09-01

The primary cilium is an essential organelle required for animal development and adult homeostasis that is found on most animal cells. The primary cilium contains a microtubule-based axoneme cytoskeleton that typically grows from the mother centriole in G0/G1 phase of the cell cycle as a membrane-bound compartment that protrudes from the cell surface. A unique system of bidirectional transport, intraflagellar transport (IFT, maintains the structure and function of cilia. While the axoneme is dynamic, growing and shrinking at its tip, at the same time it is very stable to the effects of microtubule-targeting drugs. The primary cilia found on Drosophila spermatocytes diverge from the general rules of primary cilium biology in several respects. Among these unique attributes, spermatocyte cilia assemble from all four centrioles in an IFT-independent manner in G2 phase, and persist continuously through two cell divisions. Here, we show that Drosophila spermatocyte primary cilia are extremely sensitive to microtubule-targeting drugs, unlike their mammalian counterparts. Spermatocyte cilia and their axonemes fail to assemble or be maintained upon nocodazole treatment, while centriole replication appears unperturbed. On the other hand, paclitaxel (Taxol, a microtubule-stabilizing drug, disrupted transition zone assembly and anchoring to the plasma membrane while causing spermatocyte primary cilia to grow extensively long during the assembly/elongation phase, but did not overtly affect the centrioles. However, once assembled to their mature length, spermatocyte cilia appeared unaffected by Taxol. The effects of these drugs on axoneme dynamics further demonstrate that spermatocyte primary cilia are endowed with unique assembly properties.

This study aims to propose a modification of Angle's classification for primary dentition and to assess its applicability in children from Central India, Nagpur. Modification in Angle's classification has been proposed for application in primary dentition. Small roman numbers i/ii/iii are used for primary dentition notation to represent Angle's Class I/II/III molar relationships as in permanent dentition, respectively. To assess applicability of modified Angle's classification a cross-sectional preschool 2000 children population from central India; 3-6 years of age residing in Nagpur metropolitan city of Maharashtra state were selected randomly as per the inclusion and exclusion criteria. Majority 93.35% children were found to have bilateral Class i followed by 2.5% bilateral Class ii and 0.2% bilateral half cusp Class iii molar relationships as per the modified Angle's classification for primary dentition. About 3.75% children had various combinations of Class ii relationships and 0.2% children were having Class iii subdivision relationship. Modification of Angle's classification for application in primary dentition has been proposed. A cross-sectional investigation using new classification revealed various 6.25% Class ii and 0.4% Class iii molar relationships cases in preschool children population in a metropolitan city of Nagpur. Application of the modified Angle's classification to other population groups is warranted to validate its routine application in clinical pediatric dentistry.

Antonio, Gisele Damian; Tesser, Charles Dalcanale; Moretti-Pires, Rodrigo Otavio

2014-01-01

OBJECTIVE To characterize the integration of phytotherapy in primary health care in Brazil. METHODS Journal articles and theses and dissertations were searched for in the following databases: SciELO, Lilacs, PubMed, Scopus, Web of Science and Theses Portal Capes, between January 1988 and March 2013. We analyzed 53 original studies on actions, programs, acceptance and use of phytotherapy and medicinal plants in the Brazilian Unified Health System. Bibliometric data, characteristics of the actions/programs, places and subjects involved and type and focus of the selected studies were analyzed. RESULTS Between 2003 and 2013, there was an increase in publications in different areas of knowledge, compared with the 1990-2002 period. The objectives and actions of programs involving the integration of phytotherapy into primary health care varied: including other treatment options, reduce costs, reviving traditional knowledge, preserving biodiversity, promoting social development and stimulating inter-sectorial actions. CONCLUSIONS Over the past 25 years, there was a small increase in scientific production on actions/programs developed in primary care. Including phytotherapy in primary care services encourages interaction between health care users and professionals. It also contributes to the socialization of scientific research and the development of a critical vision about the use of phytotherapy and plant medicine, not only on the part of professionals but also of the population.

2014-01-01

Primary maths is stereotypically loved by a few hairy oddballs, tolerated by most sane primary practitioners; loathed by many. With the right approach, however; the right mindset and sense of the impossible being achievable, maths can be moulded into the diamond in the rough of the primary curriculum. Enter Nick Tiley-Nunn: Britain's most imaginative, most exciting primary maths specialist. Over years of practice he has generated ideas about the teaching of maths that are so distinct, so far out and so utterly brilliant that any primary teacher struggling to grasp the nettle of teaching long division will emerge from communing with his ideas not just with some clichéd sense that ‘maths can be fun', but that it can be brilliant, life-enhancing and truly hilarious. This book presents ideas for primary maths teaching so wildly creative and so full of the joy of life that any classroom of kids will be grateful you read it.

data collected during the period 1984-1993 are calculated using the method employed in the 1950s. It is concluded that primary production in the Kattegat has increased from less than 100 g C m(-2) y(- 1) to about 200 g C m(-2) y(-1) since the 1950s. This increase is not seen during the winter months...... to be responses to increases in primary production. However, for most areas, there are insufficient data to demonstrate whether or not increases in primary production have actually occurred. In this study, the evidence for increased primary production in the Kattegat is examined by comparing primary production...... measurements from the 1950s and measurements made in the period 1984-1993. The methods employed during the two periods differ considerably. These differences and how they may affect the validity of a comparison of the results from the studies carried out in two periods are addressed. The primary production...

[Primary care in Italy].

Science.gov (United States)

Sánchez-Sagrado, T

Italy is not a country where Spanish doctors emigrate, as there is an over-supply of health care professionals. The Italian Servizio Sanitario Nazionale has some differences compared to the Spanish National Health System. The Servizio Sanitario Nazionale is financed by national and regional taxes and co-payments. There are taxes earmarked for health, and Primary Care receives 50% of the total funds. Italian citizens and residents in Italy have the right to free health cover. However, there are co-payments for laboratory and imaging tests, pharmaceuticals, specialist ambulatory services, and emergencies. Co-payments vary in the different regions. The provision of services is regional, and thus fragmentation and major inequities are the norm. Doctors in Primary Care are self-employed and from 2000 onwards, there are incentives to work in multidisciplinary teams. Salary is regulated by a national contract and it is the sum of per-capita payments and extra resources for specific activities. Responsibilities are similar to those of Spanish professionals. However, medical care is more personal. Relationships between Primary Care and specialised care depend on the doctors' relationships. Primary Care doctors are gatekeepers for specialised care, except for gynaecology, obstetrics and paediatrics. Specialised training is compulsory in order to work as general practitioner. The Italian Health Care System is a national health system like the Spanish one. However, health care professionals are self-employed, and there are co-payments. In spite of co-payments, Italians have one of the highest average life expectancy, and they support a universal and publicly funded health-care system.

Botulinum toxin for treatment of glandular hypersecretory disorders.

LENUS (Irish Health Repository)

Laing, T A

2012-02-03

SUMMARY: The use of botulinum toxin to treat disorders of the salivary glands is increasing in popularity in recent years. Recent reports of the use of botulinum toxin in glandular hypersecretion suggest overall favourable results with minimal side-effects. However, few randomised clinical trials means that data are limited with respect to candidate suitability, treatment dosages, frequency and duration of treatment. We report a selection of such cases from our own department managed with botulinum toxin and review the current data on use of the toxin to treat salivary gland disorders such as Frey\\'s syndrome, excessive salivation (sialorrhoea), focal and general hyperhidrosis, excessive lacrimation and chronic rhinitis.

Intensity-Modulated Radiation Therapy for Primary Brain Tumors

Institute of Scientific and Technical Information of China (English)

Zhong-min Wang

2004-01-01

Radiation therapy has been used to treat primary brain tumors as standard primary and/or adjunctive therapies for decades. It is difficult for conventional radiotherapy to deliver a lethal dose of radiation to the tumors while sparing surrounding normal brain due to complicated structures and multifunction in human brain. With the understanding of radiation physics and computer technology, a number of novel and more precise radiotherapies have been developed in recent years. Intensity modulated radiotherapy (IMRT) is one of these strategies. The use of IMRT in the treatment of primary brain tumors is being increasing nowadays. It shows great promise for some of primary brain tumors and also presents some problems, This review highlights current IMRT in the treatment of mainly primary brain tumors.

Loss of space in the primary dentition is considered one of the main causes of malocclusion in the permanent dentition. The purpose of this paper is to review ond summarize the indications and use of space maintainers in primary and mixed dentitions as preventive measures of future malocclusion. Two main types of space maintainers are used to maintain the space in primary ond mixed dentitions: fixed and removable appliances. Band and loop is the appliance of choice when a primary maxillary or mandibular first molar is prematurely lost. With the premature loss of a second primary molar, Nance or transpalatal (TPA) appliances can be used on the maxillary arch and the lower lingual holding arch (LLHA) for the mandibular arch.

The main objective of this study was to investigate primary teachers' subject matter knowledge in the domain of decimals and more elaborately to investigate their performance and difficulties in reading scale, ordering numbers, finding the nearest decimal and doing operations, such as addition and subtraction. The difficulties in these particular areas are analysed and suggestions are made regarding their causes. Further, factors that influence this knowledge were explored. The sample of the study was 63 primary teachers. A decimal concepts test including 18 tasks was administered and the total scores for the 63 primary teachers ranged from 3 to 18 with a mean and median of 12. Fifty per cent of the teachers were above the mean score. The detailed investigation of the responses revealed that the primary teachers faced similar difficulties that students and pre-service teachers faced. Discrepancy on teachers' knowledge revealed important differences based on educational level attained, but not the number of years of teaching experience and experience in teaching decimals. Some suggestions have been made regarding the implications for pre- and in-service teacher training.

Background. The differential diagnosis of primary breast tuberculosis with other benign or malignant conditions can be difficult with the current imaging techniques that used to recognize breast pathologies. In many cases mammographic and ultrasound characteristics of breast tuberculosis are similar to those of breast cancer. Case report. We present a case of primary breast tuberculosis, with no previous history of the disease, which was diagnosed during the operation. Conclusions. Primary breast tuberculosis can be misdiagnosed. In these cases a tuberculosis infection history is negative, the mammographic and radiological findings obscure and the mass can be misdiagnosed as carcinoma. The diagnosis is achieved after the surgical removal of the mass and histological examination of the specimen. (author)

To investigate the HPV testing recommendations of US physicians who perform cervical cancer screening. Data from the 2015 DocStyles survey of U.S. health care providers were analyzed using multivariate logistic regression to identify provider characteristics associated with routine recommendation of primary HPV testing for average-risk, asymptomatic women ≥30years old. The analysis was limited to primary care physicians and obstetrician-gynecologists who performed cervical cancer screening (N=843). Primary HPV testing for average-risk, asymptomatic women ≥30years old was recommended by 40.8% of physicians who performed cervical cancer screening, and 90.1% of these providers recommended primary HPV testing for women of all ages. The screening intervals most commonly recommended for primary HPV testing with average-risk, asymptomatic women ≥30years old were every 3years (35.5%) and annually (30.2%). Physicians who reported that patient HPV vaccination status influenced their cervical cancer screening practices were almost four times more likely to recommend primary HPV testing for average-risk, asymptomatic women ≥30years old than other providers (Adj OR=3.96, 95% CI=2.82-5.57). Many US physicians recommended primary HPV testing for women of all ages, contrary to guidelines which limit this screening approach to women ≥25years old. The association between provider recommendation of primary HPV testing and patient HPV vaccination status may be due to anticipated reductions in the most oncogenic HPV types among vaccinated women.

Small bowel tumors are rarely detected unless there is intestinal obstruction or bleeding. In the seven years 1982-1988, at Kosin Medical Center, 25 primary malignant small bowel tumors were studied radiographically with barium and / or computed tomography (CT). CT revealed gastrointestinal abnormalities in 20 patients. In ten, lesion were identified by upper G-I series, in 15 by small bowel series, and in addition, in 3 by colon enema. The most common malignant small bowel tumor was adenocarcinoma (N=15) and was next common lymphoma (N=7). On barium study, primary adenocarcinoma appeared as an irregular stricture (66.7%) and polypoid mass with intussusception was most prominent finding in lymphoma. Leiomyosarcoma appeared as an exophytic mass with excavation or ulceration. CT was found to be accurate in detecting wall thickening, complications and other associated findings. In conclusion, barium study was useful in the diagnosis of primary malignant small bowel tumor and CT was more accurate in detecting secondary findings.

Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

A future for primary care for the Greek population.

Greece is hit hard by the state debt crisis. This calls for comprehensive reforms to restore sustainable and balanced growth. Healthcare is one of the public sectors needing reform. The European Union (EU) Task Force for Greece asked the authors to assess the situation of primary care and to make recommendations for reform. Primary healthcare is especially relevant in that it might increase the efficiency of the healthcare system, and improve access to good quality healthcare. Assessment of the state of primary care in Greece was made on the basis of existing literature, site visits in primary care and consultations with stakeholders. The governance of primary care (and healthcare in general) is fragmented. There is no system of gatekeeping or patient lists. Private payments (formal and informal) are high. There are too many physicians, but too few general practitioners and nurses, and they are unevenly spread across the country. As a consequence, there are problems of access, continuity, co-ordination and comprehensiveness of primary care. The authors recommend the development of a clear vision and development strategy for strengthening primary care. Stepped access to secondary care should be realised through the introduction of mandatory referrals. Primary care should be accessible through the lowest possible out-of-pocket payments. The roles of purchaser and provider of care should be split. Quality of care should be improved through development of clinical guidelines and quality indicators. The education of health professionals should put more emphasis on primary care and medical specialists working in primary care should be (re-)trained to acquire the necessary competences to satisfy the job descriptions to be developed for primary care professionals. The advantages of strong primary care should be communicated to patients and the wider public.

This study analyzed the temporal dynamics of total microcystin LR concentrations between the years of 2012 and 2015 in the Bonete, Baygorria and Palmar hydroelectric generation reservoirs in the central region of the Negro River, Uruguay. The three reservoirs showed differents total microcystin LR concentration, with no significant differences among them. Over 20 sampling dates, the three reservoirs exhibited total microcystin LR concentrations on eight occasions that corresponded to a slight to moderate human health risk according to WHO guideline values for recreational waters. By determining the concentration of microcystin LR in cyanobacterial biomass, we identified cyanobacterial populations that occurred over time with varying degrees of toxin production (maximal 85.4 µg/mm 3 ). The microcystin LR concentration in Bonete was positively correlated with temperature (r = 0.587) and cyanobacterial biomass (r = 0.736), in Baygorria with cyanobacterial biomass (r = 0.521), and in Palmar with temperature (r = 0.500) and negatively correlated with ammonia (r = -0.492). Action is needed to reduce the presence of toxic cyanobacteria in these systems. A decrease in the use of agrochemicals and management changes in the reservoir basins could be successful long-term measures.

Patient-centered variables and their relationship to primary and team nursing have rarely been studied. In the present study the investigation focused on the following patient-centered variables: nurturance received, patient involvement, and frequency of nurse-patient contacts. Baseline observational data were collected on 12 adult medical patients experiencing team nursing care. A primary nursing care approach was then implemented on the same nursing unit, and 6 months later 12 patients were observed under this system. Patients were directly observed 24 hours a day for 5 days of hospitalization and audiotaped, using a specimen record method. This method produced transcripts that were coded for nurturance, involvement, and nurse-patient contacts. Results of the study showed that there were no differences between primary and team nursing care groups in the number of contacts, nurturance, or patient involvement with all nursing personnel or with professional nurses. However, when the primary group was adjusted to include only those patients for whom primary nursing care was fully implemented, the primary group received more nurturance (p less than .05) and had a tendency to be more active involved than did the team group (p less than .10). These findings indicate that the institution of primary nursing care is related to increased quality of nursing care.

While correlation of developmental stage with embryonic age of the human primary dentition has been well documented, the available information regarding the differentiation timing of the primary teeth was largely based on the observation of initial mineralization and varies significantly. In this study, we aimed to document precise differentiation timing of the developing human primary dentition. We systematically examined the expression of odontogenic differentiation markers along with the formation of mineralized tissue in each developing maxillary and mandibular teeth from human embryos with well-defined embryonic age. We show that, despite that all primary teeth initiate development at the same time, odontogenic differentiation begins in the maxillary incisors at the 15th week and in the mandibular incisors at the 16th week of gestation, followed by the canine, the first primary premolar, and the second primary premolar at a week interval sequentially. Despite that the mandibular primary incisors erupt earlier than the maxillary incisors, this distal to proximal sequential differentiation of the human primary dentition coincides in general with the sequence of tooth eruption. Our results provide an accurate chronology of odontogenic differentiation of the developing human primary dentition, which could be used as reference for future studies of human tooth development.

Objective: To evaluate the value of 18 F-deoxyglucose (FDG) positron emission tomography (PET) in detecting the primary focus of metastatic cancer with an unknown primary. Methods: Twenty-nine patients with various histological types of metastases from an unknown primary after extensive conventional diagnostic work-up were studied. After intravenous 370 MBq FDG, whole body scan was made 50 minutes after injection. The results of FDG PET were compared with those of CT or MRI. Results: With FDG PET, the primary tumors were identified in 13 patients and confirmed by pathology. The corresponding detection rate was 44.8% (13/29) as compared with 27.6% (8/29) by CT or MRI. In addition, 26 metastases were discovered by FDG PET whole body imaging but only 13 were found by CT or MRI. During 2-13 months' follow-up, the mortality rates were 15.4%(2/13) and 42.9%(6/14) for patients with the primary tumor identified or unidentified. Conclusions: FDG PET is valuable in staging, selecting appropriate treatment protocol and predicting prognosis for patients suffering from metastatic cancers with an unknown primary

Endodontic treatment in primary teeth can be challenging and time consuming, especially during canal preparation, which is considered one of the most important steps in root canal therapy. The conventional instrumentation technique for primary teeth remains the "gold-standard" over hand instrumentation, which makes procedures much more time consuming and adversely affects both clinicians and patients. Recently nickel-titanium (Ni-Ti) rotary files have been developed for use in pediatric endodontics. Using rotary instruments for primary tooth pulpectomies is cost effective and results in fills that are consistently uniform and predictable. This article reviews the use of nickel-titanium rotary files as root canal instrumentation in primary teeth. The pulpectomy technique is described here according to different authors and the advantages and disadvantages of using rotary files are discussed.
