This document discusses different types of partial foot prostheses and transtibial prostheses. It describes the purposes of partial foot prostheses which are to restore foot function, simulate the shape of the missing foot segment, and improve the appearance of shoes. It then discusses different types of prosthetic feet including non-articulated feet like SACH feet, single axis feet, and multiple axis feet. For transtibial prostheses, it describes the main components which are the foot-ankle assembly, shank, socket, and suspension methods like cuffs, sleeves, and corsets. It provides details on the materials, movements, and advantages of each component type.

The patellar-tendon-bearing socket is made of laminated or molded plastic that provides an intimate fit over the entire area of the amputated portion of the limb, including the distal end. The anterior wall of the socket is high enough to encompass the distal half of the patella while the posterior wall rises slightly higher than the apex of the in- ward bulge of the socket at the level of the patellar tendon. The medial and lateral walls are slightly higher than the anterior wall to control mediolateral forces applied to the stump, thereby enhancing stability, in this plane. The basic PTB socket also incorporates a soft insert liner
Provide:
The PTB socket provides total contact with the stump.
This feature helps to prevent edema, provides some additional support area (although the end of the stump cannot tolerate much pressure), and probably provides better sensory feedback to the wearer because of the greater area of contact between the amputated limb and the socket
Air cushion Socket
One of the designs, the PTB air-cushion socket, consists of an elastic inner sleeve (stockinette impregnated with silicone rubber) within a rigid outer shell and cap. A sealed chamber between these two walls contains air at atmospheric pressure. Distal support is provided by the tension of the sleeve itself and by compression of the air sealed in the chamber.
The advantages of the air-cushion socket are that is offers a possibility for higher distal loading,
Maintains distal contact even when limb volume changes slightly,
Lessens skin damage due to stretching of skin against an unyielding surface.
The increased distal loading may enhance circulation by decreasing the need for more constrictive proximal loading.
Two major difficulties are that it is complicated to fabricate and, once completed, modifications are very difficult.
Other Socket Variations
In addition to the variations-described above, which relate primarily to weight-bearing characteristics.
Other variations of the basic PTB socket involve the upward extension of the anterior, medial, and lateral walls to provide al- ternate means of suspension.
Since these designs relate to suspension, they are described in the section that follows.
Supracondylar Suprapetellar System
The basic PTB prosthesis is suspended by means of a supracondylar cuff ,which is attached to the socket in the posteromedial and posterolateral areas, and encircles the thigh just above the femoral epicondyles and patella
. The supracondylar cuff serves-primarily to retain the prosthesis on the stump.
It provides only slight assistance for mediolateral stability but does resist forces that tend to force the knee into hyperextension.
Most amputees, with the possible exception of those with very-short or painful stumps, find the stump-socket pressures well within their tolerance with this type of suspension.
The supracondylar/suprapatellar (SC/SP) suspension system has similarly high medial and lateral.
Disarticulation prosthesis
Individuals with knee and hip disarticulation wear prostheses that include the same distal components as prostheses for lower levels.
Any prosthetic foot can be used with either an endoskeleton or exoskeleton shank. The major distinction, therefore, is in the proximal portion of the prostheses.
Plastic molded to provide weightbearing on the ipsilateral ischial tuberosity and buttocks. The person with transpelvic amputation who does not retain the ipsilateral tuberosity or iliac crest has a socket with a higher proximal Trimline, sometimes encompassing the lower thorax.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

2. Purpose:
Restore foot function particularly in walking
Simulate shape of the missing foot segment
Pt lost one or more toes may simply pad the
toe section of shoe…… to improve
appearance of the upper portion of the shoe.
Standing is not affected, assuming the
metatarsal heads remain
3. When individual walks, late stance will be less
forceful, particularly if phalanges of the great toe
are absent.
An arch support ……. Maintain alignment of
amputated foot
Transmetatarsal amputation:- disturbs foot
appearance
Prosthesis prevent shoe from developing
unnatural crease
Bears most weight on heels
Prosthesis plastic socket for remainder of the foot
Rigid plate…….. Restore
Bottom of prosthesis…… rocker bar effects
4. Amputation or disarticulation ….. Through
tarsals poses additional problem of retaining
small foot during swing phase
Prosthesis used ……. Transmetatarsal
amputation is augmented with plastic calf
shell, which is strapped around the leg.
5. Transtibial prosthesis
Retains anatomical knee and its motor ansd
sensory function
Cause…. ?
Syme’s amputation limb is longer than….?
Improving prosthetic control
Syme’s amputation…… tolerate more weight
through end of the limb
Includes…foot-ankle assembly and socket
Transtibial…… suspension and shank
component
6. 1) foot-ankle assembly
Pros foot restores general contours
Absorbs shock
Many assemblies also provide slight motion in
frontal & transverse plane
Non articulated feet:-
Us ….. Most popular type
Lighter in weight, more durable, more
attractive , some versions are made to suit
high heeled shoes
7. SACH
most commonly prescribe foot
Consist wooden or metal keel …. Terminates at a
point corresponding to MTPJ.
Keel… covered with rubber
Post portion is resilient , absorbs shock, permit
plantarflexion in early stance phase
Late stance….. Hyperextension
Manufactured in a wide range of sizes…
Having heel cushion….. Allows a very small
amount of medial-lateral and transverse motion
8. Other nonarticulated feet
Version of SACH is (SAFE)
Stationary attachment flexible endoskeleton foot
Heavier and expensive than SACH
It has rigid ankle block joined to post portion of
keel at 45 degree angle. Comparable to
anatomical subtalar jt
The junction permits the wearerto maintain the
contact with moderately uneven terrains, bec of
greater range of medial-lateral range of motion
permitted in the rear foot.
9. large Variety of prosthetic feet are available…..
Selection depends on needs of individual like
wearers activity level, weight, level of
amputation as well as length and shape of the
amputation.
10. Single axis feet
It permits plant and dorsif
Multiple-axis feet:
Move slightly in all planes to aid the wearer in
maintaining max contact with walking surface.
Heavier and less durable
Rotators:-
Component placed above the prosthetic foot to
absorb shock .
Most often used with single axis feet and those
with transfemoral amputation.
11. 2) Shank
Substitute for human leg, restoring leg length
and shape
Located above foot ankle assembly and below
the socket
Which type of prost does not have shank…. ?
Two types exoskeleon
Endoskeleton
Which one is more durable and more
frequently prescribe??
12.
13.
14.
15.
16. 3) socket
The amputated limb fits into a plastic
receptacle called the socket.
Socket is designed to contact all portions of
the amputated limb for maximum distribution of
load , assist venous blood circulation, provide
tactile feedback
Sockets are custom made of plastic molded
over a model of the pts amputation limb
The model may be produced from a plaster
cast of the amputation limb or by (CAD-CAM)
17. Socket is aligned on shank.
Two types
Lined socket
Unlined socket
a) Lined socket:
transtibial socket is generally includes a
resilient polyethylene foam liner.
Cushioning the amputation limb
The removable liner facilitates alteration of the socket
size.
Liner however adds the bulk of the prosthesis and is a
heat insulator…….. Uncomfortable in summer
18. b) Unlined socket
Sometimes referred as hard socket
Misnomer
b/c pt has a soft interface provided by socks or
a sheath worn with unlined socket
Occasionally a resilient pad is placed ……
bottom ….to Cushion distal end of ampu limb
More satisfactory choice……. Stabilized b/c It
is easy to wear but difficult to alter the shape
19. 4) Suspension
During the swing phase of walking, the
prosthesis requires some form of suspension
to hold it in place.
Cuff Variant :-
The cuff, a leather variant encircling the thigh
immediately above the femoral epicondyles,
permits the user to adjust the snugness of
suspension easily.
An alternative to the cuff is a rubber sleeve, a
tubular component that covers the proximal
socket and the distal thigh.
20.
21. Distal attachment
Very secure suspension is achieved with the
use of a silicone sheath with a distal metal pin.
The sheath clings the skin. The user inserts
the sheathed limb into the prosthesis, guiding
the attached pin into a receptacle in the socket
. During swing phase, the pin mechanism
prevents the prosthesis from slipping.
22. Brim variant
The prosthesis may be suspended by its socket
walls extended proximally. With supracondylar
(SC) suspension , the med & lat walls extended
above the femoral epicondyles. The medial wall
has a plastic wedge. When donning the
prosthesis, the client removes the wedge, places
the amputation limb in the socket, then places the
wedge b/w the socket and the medial epicondyle
to retain the prosthesis on the limb.
supracondylar (SC) suspension increases med lat
stability of pros.
More difficult to fabricate, more expensive and not
readily adjustable.
23. Thigh corset
Some individuals with very sensitive skin may
benefit from thigh corset suspension. Metal hinges
attach distally to the medial and lateral aspects of
the socket and proximally to a leather or flexible
plastic corset.
Corset heights vary and may reach the ischial
tuberosity for maximum weight relief on the
amputated limb.
Prolonged use of a thigh corset produces
pressure atrophy of the thigh. A prosthesis with
corset suspension is more difficult to don…….
Fasten laces or pressure loop straps.
24.
25. Syme’s suspension
Syme’s prosthesis is suspended by the contours of its
brims and socket walls, without a cuff or other
suspension mechanism.
Vacuum-Assisted Socket System:-
Used less frequently with transtibial
amputation owing to reduced surface area of the
residual limb.
Uniquely combines use of a pump, linear and sleeve
to achieve elevated vacuum in an airtight
environment.
The vacuum is believed to promote fluid exchange,
reduce moisture buildup, regulate volume fluctuations
and increase proprioceptive awareness of where the
limb is in space.
