Background: There exists little information in the relevant literature regarding tunnel enlargement after posterior cruciate ligament (PCL) reconstruction (PCLR). Purpose: To sequentially evaluate tunnel enlargement and radiographic posterior laxity through double-bundle PCLR using autologous hamstring tendon grafts. Study Design: Case series; Level of evidence, 4. Methods: We prospectively analyzed 13 patients who underwent double-bundle PCLR for an isolated PCL injury. Three-dimensional computed tomography images were obtained at 3 weeks, 6 months, and 1 year postoperatively, and the tunnel enlargement was calculated by sequentially comparing the cross-sectional areas of the bone tunnels. We also sequentially measured radiographic posterior laxity. The correlation between the tunnel enlargement ratio and the postoperative increase in posterior laxity was evaluated. Results: The cross-sectional area at the aperture in each tunnel significantly increased from 3 weeks to 6 months ( P < .003), but it did not continue doing so thereafter. The 6-month tunnel enlargement ratios of the femoral anterolateral tunnel, the femoral posteromedial tunnel, the tibial anterolateral tunnel, and the tibial posteromedial tunnel were 31.6% ± 23.5%, 90.3% ± 54.7%, 30.5% ± 26.8%, and 49.6% ± 37.0%, respectively, while the corresponding ratios at 1 year were 28.1% ± 19.8%, 83.1% ± 56.9%, 26.8% ± 32.8%, and 47.6% ± 39.0%, respectively. The posterior laxity was 9.0 ± 4.0 mm, −1.5 ± 2.3 mm, 3.4 ± 2.0 mm, and 3.9 ± 1.9 mm, preoperatively, immediately after surgery, 6 months and 1 year postoperatively, respectively. From the immediate postoperative period, the posterior laxity significantly increased at 6 months postoperatively ( P < .001), but it did not thereafter. The postoperative increase in posterior laxity had a significant positive correlation with the anterolateral tunnel enlargement ratio in both femoral and tibial tunnels at 6 months (ρ = 0.571-0.699; P = .011-.041) and 1 year (ρ = 0.582-0.615; P = .033-.037). Conclusion: Tunnel enlargement after PCLR mainly occurred within 6 months, with no progression thereafter. The anterolateral tunnel enlargement positively correlated with postoperative increase in posterior laxity.

Background: Acne vulgaris is a common condition with a prevalence of over 90% among adolescents and post- acne scarring is a well known sequelae. Different types of scars (ice pick, boxcar, and rolling scars) warrant a customized approach of treatment for each type. We propose a novel treatment of atrophic acne scars using combination of subcision and microneedling. Methods: Ten consecutive patients of skin types III - IV with moderate and severe facial acne scarring received three sequential subcision and microneedling treatments after informed consent over a period of three months with an interval of 4 weeks between each session. Goodman and Baron’s qualitative and quantitative acne scar grading systems along with side by side comparison of pre operative and post operative photographs were used for assessment at the end of three sessions of the combination procedure. Results: Estimation of improvement with Goodman and Baron’s Global qualitative acne scarring system , we found good results in patients with Grades 3 and 4 acne scars. Out of 7 patients with grade 4 scars, 29% showed improvement by 2 grades and 71% showed improvement by 1 grade and all the 3 patients with grade 3 scars showed improvement by 1 grade. Quantitative assessment showed 30% patients had minimal improvement, 50% had moderate improvement and 20% had good improvement in scars.  Adverse effects were transient pain, erythema and oedema. Conclusion: Subcision and microneedling are simple and inexpensive office procedures which in combination are well tolerated and are efficacious in treatment of moderate and severe acne scars.

Invasive Method

Introduction: Acne is an extremely prevalent condition. The healing of active acne lesions may result in the development of scars. Atrophic scars are the main scars caused by acne and result from the degradation of collagen fibers. Carboxytherapy is a minimally invasive method that involves the application of carbon dioxide subcutaneously through small infiltrations in the skin, which improves scar tissue by increasing collagen's deposition and reorganization. The aim of this study is to review the role of carboxytherapy in the treatment of atrophic facial scars, alone or in combination with other techniques. Methods: A literature search was conducted on several databases using MeSH terms “carboxytherapy”, “carbon dioxide/therapy” and “wounds” for guidelines, systematic reviews, randomized controlled trials, and observational studies, published over the last 20 years in Portuguese, English or Spanish languages. Results: A total of 129 articles were retrieved, of which four experimental studies and one case series were selected. Comparing the techniques of microneedling and carboxytherapy, both were considered non-invasive treatment modalities with equal effectiveness, tolerability and safety, resulting in similar histopathological changes. On the other hand, despite the improvement of acne scars in both treatment modalities, the results were significantly better in favor of carbon dioxide fractional laser, despite having more side effects than carboxytherapy. When these techniques are combined and carboxytherapy is used as a subcision method, there is a more marked and rapid improvement in the appearance of acne scars. Discussion: Carboxytherapy is a promising modality in the treatment of atrophic acne scars, alone or in combination with other techniques.

<p class="abstract">Acne vulgaris is a common skin disorder affecting 80% of people between 11-30 years of age with many experiencing some degree of scarring. Pulsed wave carbon dioxide (CO2) laser resurfacing is a recent addition in armamentarium of treatment options for acne scars. This study focuses on one of the most common type of acne complication - atrophic scars treated with pulsed wave carbon dioxide laser. To evaluate efficacy of pulsed carbon dioxide laser for treatment of mild to moderate atrophic facial acne scars. 10 subjects (6 male and 4 females, aged 22-35 years) with skin type III-V and atrophic acne scars were treated with 4 sessions of carbon dioxide non-ablative laser resurfacing on 6 weeks interval. 7 out of 10 subjects in our study perceived an excellent to good improvement with 2 patients showing fair improvement and 1 patient with no improvement. Adverse effects were limited to prolonged erythema (two patients), and post-inflammatory hyperpigmentation (three patient). Excellent to good clinical improvement observed in 70% of patients with acne scars. This underscore pulsed carbon dioxide laser’s effectiveness in the treatment of mild to moderate atrophic acne scars.</p>

The aim of this study is to assess the outcome of Pedicled extended Lateral arm flaps (PELAF) for coverage of defects of the hand and forearm. 09 patients were included in this study from January, 2005 to February 2009. Patients with hand defects with or without extension up to the forearm, resurfaced with this flap, were reviewed for this case series. Eight flaps were cross arm, i.e. for defects in the contra lateral hand and 01 was used to cover the cubital fossa of the same limb. Ages of the patients ranged from 23-46 years, 01 female and 08 male. 08 patients were diabetic while 01 was non diabetic. Nine cases were managed by extended lateral arm flap or a standard lateral forearm flap. Postoperative periods of all the patients were uneventful. Then pedicle was divided after 3 weeks for the cross arm flap group. For patients with wounds on the hand, wrist and forearm pedicled lateral and extended lateral arm flap provides an excellent thin, supple and reliable option for coverage. Cross Lateral arm flap is one of the few local options available with good colour and contour match and requires no sacrifice of major blood vessel.Medicine Today 2017 Vol.29(2): 9-12

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

During the earliest stage of oocyte development in the limpet, Acmea scutum, Golgi complexes are small, few and randomly dispersed in the cytoplasm. As growth proceeds, the Golgi complexes increase in size and number and migrate to the periphery of the cell. At this time, fibrous structures resembling striated rootlets occur associated with the Golgi complexes. Only one fibrous structure appears to be associated with a Golgi complex.The fibers are periodically cross banded with an average of 4 dense fibrils and 6 lighter fibrils per period (Fig. 1). The cross fibrils have a center to center spacing of about 7 run which appears to be the same as that of the striated rootlets of the gill cilia in this animal.

The energy distribution in an electron; beam from an electron gun provided with a biased Wehnelt cylinder was measured by a retarding potential analyser. All the measurements were carried out with a beam of small angular divergence (<3xl0-4 rad) to eliminate the apparent increase of energy width as pointed out by Ichinokawa.The cross section of the beam from a gun with a tungsten hairpin cathode varies as shown in Fig.1a with the bias voltage Vg. The central part of the beam was analysed. An example of the integral curve as well as the energy spectrum is shown in Fig.2. The integral width of the spectrum ΔEi varies with Vg as shown in Fig.1b The width ΔEi is smaller than the Maxwellian width near the cut-off. As |Vg| is decreased, ΔEi increases beyond the Maxwellian width, reaches a maximum and then decreases. Note that the cross section of the beam enlarges with decreasing |Vg|.

The only form of cellulose which could unequivocally be ascribed to the animal kingdom is the tunicin that occurs in the tests of the tunicates. Recently, high-resolution solid-state l3C NMR revealed that tunicin belongs to the Iβ form of cellulose as opposed to the Iα form found in Valonia and bacterial celluloses. The high perfection of the tunicin crystallites led us to study its crosssectional shape and to compare it with the shape of those in Valonia ventricosa (V.v.), the goal being to relate the cross-section of cellulose crystallites with the two allomorphs Iα and Iβ.In the present work the source of tunicin was the test of the ascidian Halocvnthia papillosa (H.p.). Diffraction contrast imaging in the bright field mode was applied on ultrathin sections of the V.v. cell wall and H.p. test with cellulose crystallites perpendicular to the plane of the sections. The electron microscope, a Philips 400T, was operated at 120 kV in a low intensity beam condition.
